Abstract
BACKGROUND Intraocular inflammation, commonly referred to as uveitis, is a prevalent ocular disease. The categorization of uveitis may be based on the prevailing anatomical site, which includes anterior, intermediate, and posterior uveitis. There exists a significant body of evidence indicating that T cells play a pivotal role in the pathogenesis of autoimmune uveitis. In addition to the presence of T cells, an elevation in levels of inflammatory cytokines and a reduction in regulatory cytokines were also noted. The primary pharmacological interventions for uveitis comprise of corticosteroids, methotrexate, anti-vascular endothelial growth factor (VEGF) agents, anti-tumor necrosis factor-alpha (TNF-α) antibodies, and sirolimus. These medications offer prompt alleviation for inflammation. Nevertheless, prolonged administration of corticosteroids invariably leads to unfavorable adverse reactions. The traditional topical corticosteroids exhibit certain limitations, including inadequate transcorneal permeation and low corneal retention, leading to reduced ocular bioavailability. Consequently, there is a growing inclination towards the creation of innovative steroid drug delivery systems with the aim of reducing the potential for adverse effects, while simultaneously enhancing the drug's corneal permeation and retention. CONCLUSION This review is an attempt to compile all the research work done so far in this field and provides a brief overview of the global efforts to develop innovative nanocarrier-based systems for corticosteroids.

Abstract
The current piece of research intends to evaluate the potential of combining etodolac with deformable-emulsomes, a flexible vesicular system, as a promising strategy for the topical therapy of arthritis. The developed carrier system featured nanometric dimensions (102 nm), an improved zeta potential (- 5.05 mV), sustained drug release (31.33%), and enhanced drug deposition (33.13%) of DE-gel vis-à-vis conventional system (10.34% and 14.71%). The amount of permeation of the developed nano formulation across skin layers was demonstrated through CLSM and dermatokinetics studies. The safety profile of deformable-emulsomes has been investigated through in vitro HaCaT cell culture studies and skin compliance studies. The efficacy of the DE-gel formulation was sevenfold higher in case of Xylene induced ear edema model and 2.2-folds in CFA induced arthritis model than that of group treated with conventional gel (p < 0.01). The main technological rationale lies in the use of phospholipid and sodium deoxycholate-based nanoscale flexible lipoidal vesicles, which effectively encapsulate drug molecules within their interiors. This encapsulation enhances the molecular interactions and facilitates the transportation of the drug molecule effectively to the target-site. Hence, these findings offer robust scientific evidence to support additional investigation into the potential utility of flexible vesicular systems as a promising drug delivery alternative for molecules of this nature.

Abstract
The current study was undertaken to evaluate the efficacy of a novel nano-lipoidal eye drop formulation of triamcinolone acetonide (TA) for the topical treatment of uveitis. The triamcinolone acetonide-loaded nanostructured lipid carriers (cTA-NLC) were developed by employing 'hot microemulsion method' using biocompatible lipids, which exhibited a sustained release nature and enhanced efficacy when evaluated in vitro. The in vivo efficacy of this developed formulation was tested on Wistar rats, and a single-dose pharmacokinetic study was conducted in rabbits. The eyes of animals were examined for any signs of inflammation using the 'Slit-lamp microscopic' method. The aqueous humor collected from the sacrificed rats was tested for total protein count and cell count. The total protein count was determined using BSA assay method, while the total cell count was determined by Neubaur's hemocytometer method. The results showed that the cTA-NLC formulation had negligible signs of inflammation, with a clinical score of uveitis 0.82 ± 0.166, which is much less than control/untreated (3.80 ± 0.3) and free drug suspension (2.66 ± 0.405). The total cell count was also found to be significantly low for cTA-NLC (8.73 ± 1.79 × 105) as compared to control (52.4 ± 7.71 × 105) and free drug suspension (30.13 ± 3.021 × 105). Conclusively, the animal studies conducted showed that our developed formulation holds the potential for effective management of uveitis.

Abstract
The entire world has recently been witnessing an unprecedented upsurge in microbial lung infections. The major challenge encountered in treating the same is to ensure the optimum drug availability at the infected site. Aerosolization of antimicrobials, in this regard, has shown immense potential owing to their localized and targeted effect. Efforts, therefore, have been undertaken to systematically develop lung-phosphatidylcholine-based lipid nanovesicles of voriconazole for potential management of the superinfections like aspergillosis. LNVs, prepared by thin-film hydration method, exhibited a globule size of 145.4 ± 19.5 nm, polydispersity index of 0.154 ± 0.104 and entrapment efficiency of 71.4 ± 2.2% with improved in vitro antifungal activity. Aerodynamic studies revealed a microdroplet size of ≤5 μm, thereby unraveling its promise to target the physical barrier of lungs effectively. The surface-active potential of LNVs, demonstrated through Langmuir-Blodgett troughs, indicated their ability to overcome the biochemical pulmonary surfactant monolayer barrier, while the safety and uptake studies on airway-epithelial cells signified their immense potential to permeate the cellular barrier of lungs. The pharmacokinetic studies showed marked improvement in the retention profile of voriconazole in lungs following LNVs nebulization compared to pristine voriconazole. Overall, LNVs proved to be safe and effective delivery systems, delineating their distinct potential to efficiently target the respiratory fungal infections.

Abstract
The current studies investigate the application of quality by design-enabled type III self-emulsifying delivery system (Type III-SEDDS) of sorafenib tosylate (SFN) in improving its biopharmaceutical attributes. Initially, lipidic and emulsifying excipients were selected by carrying out solubility and phase titration experiments. After screening studies using Taguchi OA design, Type III-SEDDS were further optimised using D-optimal mixture design. The prepared formulations were assessed for globule size, zeta potential and percent of drug release. Following graphical optimisation, the optimum formulation was earmarked and further supersaturated to form saturated Type III-SEDDS (Sat-Type III-SEDDS) using a combination of HPMC and PVP to improve the stability of the formulation for a prolonged period. In vitro drug release of Type III-SEDDS study indicated approximately 8-fold improvement in dissolution rate over the pure powder drug. Cell uptake studies demonstrated higher uptake of dye-loaded Type III-SEDDS formulations in Caco-2 cells vis-à-vis plain dye. Cytotoxicity assay on Hep G2 cells revealed significant reduction in cell growth with Type III- and Sat-Type III-SEDDS vis-à-vis the pure drug. Furthermore, in situ permeation studies carried out using Wistar rats exhibited nearly 8.3- to 10.2-fold augmentation in permeation and absorption parameters of the drug from the Type III- and Sat-Type III-SEDDS, respectively, vis-à-vis the pure drug. Pharmacokinetic studies indicated nearly 3.98- and 3.62-fold improvement in AUC0-72, and 8.01- and 5.42-fold in Cmax, along with 0.25-fold decrease in Tmax of the drug from Type III- and Sat-Type III-SEDDS, respectively, in comparison with the SFN suspension. Furthermore, high degree of level A linear correlation was established between fractions of drug dissolved (in vitro) and of drug absorbed (in vivo) at the corresponding time points for Sat-Type III-SEDDS and pure drug, whereas the Type III-SEDDS exhibited a nonlinear relationship. Stability studies indicated the robustness of Sat-Type III-SEDDS, when stored at 25 °C for 3 months. Overall, the manuscript documents the successful systematic development of SFN-loaded Sat-Type III-SEDDS with distinctly improved biopharmaceutical performance. Graphical abstract.

Abstract
BACKGROUND Lumefantrine (LMF) is first-line antimalarial drug, possesses activity against almost all human malarial parasites, but the in vivo activity of this molecule gets thwarted due to its low and inconsistent oral bioavailability (i.e. 4-12%) owing to poor biopharmaceutical attributes. METHODS Lumefantrine phospholipid complex (LMF-PC) was prepared by rota-evaporation method following job's plot technique for the selection of apt stoichiometric ratios. Docking studies were carried out to determine the possible interaction(s) of LMF with phosphatidylcholine analogue. Comparative in vitro physiochemical, solid-state characterization, MTT assay, dose-response on P. falciparum, in vivo efficacy studies including pharmacokinetic and chemosuppression on NK-65 P. berghei infected mice were carried out. RESULTS Aqueous solubility was distinctly improved (i.e. 345 times) with phospholipid complex of LMF. Cytotoxicity studies on Hela and fibroblast cell lines demonstrated safety of LMF-PC with selectivity indices of 4395 and 5139, respectively. IC50 value was reduced almost 2.5 folds. Significant enhancement in Cmax (3.3-folds) and AUC (2.7-folds) of rat plasma levels indicated notable pharmacokinetic superiority of LMF-PC over LMF suspension. Differential leukocytic count and cytokine assay delineated plausible immunoregulatory role of LMF-PC with nearly 98% chemosuppression and over 30 days of post-survival. CONCLUSION Superior antimalarial efficacy and survival time with full recovery of infected mice revealed through histopathological studies.

Abstract
BACKGROUND Ceftazidime, a third-generation cephalosporin, is widely used in the treatment of lung infections, often given as "off-label" nebulization. There is a need to develop a sensitive and robust analytical method to compute aerodynamic properties of ceftazidime following nebulization. OBJECTIVE The current study entails development of a simple, accurate, and sensitive HPLC method for ceftazidime estimation, employing the principles of analytical quality-by-design (AQbD) and Monte Carlo simulations. METHOD Selection of critical material attributes (CMAs) affecting method performance was accomplished by factor screening exercises. Subsequently, the influential CMAs, i.e., mobile phase ratio and flow rate, were systemically optimized using a face-centered cubic design for the chosen critical analytical attributes (CAAs). The factor relationship(s) between CMAs and CAAs was explored employing a 3 D-response surface and 2 D-contour plots, followed by numerical as well as graphical optimization, for establishing the optimal chromatographic conditions. The obtained method operable design region was validated by Monte Carlo simulations for defect rate analysis. RESULTS The optimized HPLC conditions for estimating ceftazidime were acetonitrile to acetic acid solution (75:25) as mobile phase at a flow rate of 0.7 mL/min, leading to Rt of 4.5 min and peak tailing ≤2. Validation studies, as per International Conference on Harmonization Q2(R1) guidance, demonstrated high sensitivity, accuracy, and efficiency of the developed analytical method with an LOD of 0.075 and LOQ of 0.227 µg/mL. Application of this chromatographic method was extrapolated for determining aerodynamic performance by nebulizing ceftazidime at a flow rate of 15 L/min using a next-generation impactor. The study indicated superior performance, sensitivity, and specificity of the developed analytical system for quantifying ceftazidime. CONCLUSIONS Application of an AQbD approach, coupled with Monte Carlo simulations, aided in developing a robust HPLC method for estimationof ceftazidime per se and on various stages of impactor. HIGHLIGHTS (i) QbD-enabled development of robust RP-HPLC method for ceftazidime quantification, (ii) Analytical method optimization employing Risk Assessment and Design of Experiments, (iii) Design space verification and defect rate analysis using Monte Carlo simulations, (iv) Chromatographic method validation as per ICH Q2 R1 guidelines and (v) Quantitative estimation of ceftazidime on various stages of impactor.

Abstract
Ferulic acid (FA) is a ubiquitous natural plant bioactive with distinctive promise in neurodegenerative disorders. However, its therapeutic efficacy gets compromised owing to its poor aqueous solubility, inadequate permeability across lipophilic barriers, and extensive first-pass metabolism. The current studies, therefore, were undertaken to systematically develop chitosan-coated solid lipid nanoparticles (SLNs) using QbD paradigms for improved efficacy of FA in the management of Alzheimer's disease (AD). SLNs of FA were formulated employing Compritol as lipid and polysorbate 80 as surfactant and optimised using a 32 Central Composite Design (CCD). The optimized formulation, surface-coated with chitosan using ionic gelation, exhibited particle size of 185 nm, entrapment efficiency of 51.2 % and zeta potential of 12.4 mV. FTIR and DSC studies verified the compatibility of FA with formulation excipients, PXRD construed significant loss of drug crystallinity, while FESEM depicted existence of uniform spherical nanoparticles with little aggregation. Notable improvement in ex vivo mucoadhesion and permeation studies using goat nasal mucosa, coupled with extension in in vitro drug release, was obtained with SLNs. Substantial improvement with SLNs in cognitive ability through the reduction in escape latency time during behavioural studies, together with significant improvement in various biochemical parameters and body weight gain was observed in AD-induced rats. Histopathological images of different rat organs showed no perceptible change(s) in tissue morphology. Overall, these preclinical findings successfully demonstrate improved anti-AD efficacy, superior nasal mucoadhesion and permeation, extended drug release, improved patient compliance potential, safety and robustness of the developed lipidic nanoconstructs of FA through intranasal route.

Abstract
BACKGROUND The combination therapy of Isotretinoin (ITR) and antibacterial formulations administered through topical route suffer from several limitations including reduced therapeutic efficacy and low patient-compliance. EXPERIMENT The present study aimed to develop biocompatible lipid-based mixed micelles of ITR in combination with Clindamycin phosphate (CLIN) employing self-assembly method to improve its skin delivery, photostability, biocompatibility and pharmacodynamic efficacy. RESULTS The MTT assay and cellular uptake studies showed non-cytotoxic effect to HaCat cell lines. The zone of inhibition studies conducted in Propionibacterium acnes provides the first literature evidence to support the antimicrobial property of Isotretinoin and Tretinioin. The nano-sized carriers offered (19.3 ± 1.03 nm particle size with -3.12 mV zeta potential) enhanced permeation, skin retention, pre-clinical efficacy and significant skin biocompatibility. The testosterone-induced acne model proved superior pharmacodynamic efficacy of lab developed formulation vis-à-vis marketed products of both the drugs. The results were further confirmed by the histopathological studies of respective skin samples treated with different formulations. CONCLUSION The lab developed lipid-based micellar formulation of ITR and CLIN offers a better strategy for the combined delivery of unstable molecules like ITR and CLIN in acne management.

Abstract
BACKGROUND Incidence of pulmonary aspergillosis is rising worldwide, owing to an increased population of immunocompromised patients. Notable potential of the pulmonary route has been witnessed in antifungal delivery due to distinct advantages of direct lung targeting and first-pass evasion. The current research reports biomimetic surface-active lipid-polymer hybrid (LPH) nanoparticles (NPs) of voriconazole, employing lung-specific lipid, i.e., dipalmitoylphosphatidylcholine and natural biodegradable polymer, i.e., chitosan, to augment its pulmonary deposition and retention, following nebulization. RESULTS The developed nanosystem exhibited a particle size in the range of 228-255 nm and drug entrapment of 45-54.8%. Nebulized microdroplet characterization of NPs dispersion revealed a mean diameter of ≤ 5 μm, corroborating its deep lung deposition potential as determined by next-generation impactor studies. Biophysical interaction of LPH NPs with lipid-monolayers indicated their surface-active potential and ease of intercalation into the pulmonary surfactant membrane at the air-lung interface. Cellular viability and uptake studies demonstrated their cytocompatibility and time-and concentration-dependent uptake in lung-epithelial A549 and Calu-3 cells with clathrin-mediated internalization. Transepithelial electrical resistance experiments established their ability to penetrate tight airway Calu-3 monolayers. Antifungal studies on laboratory strains and clinical isolates depicted their superior efficacy against Aspergillus species. Pharmacokinetic studies revealed nearly 5-, 4- and threefolds enhancement in lung AUC, Tmax, and MRT values, construing significant drug access and retention in lungs. CONCLUSIONS Nebulized LPH NPs were observed as a promising solution to provide effective and safe therapy for the management of pulmonary aspergillosis infection with improved patient compliance and avoidance of systemic side-effects.

Abstract
The present work describes the systematic development of a simple, rapid, sensitive, robust, effective and cost-effective reversed-phase high performance liquid chromatographic method for quantitative analysis of ferulic acid using analytical quality by design paradigms. Initially, apt wavelength for the analysis of ferulic acid was selected employing principal component analysis as the chemometric tool. An Ishikawa fishbone diagram was constructed to delineate various plausible variables influencing analytical target profile, viz. peak area, theoretical plate count, retention time and peak tailing as the critical analytical attributes. Risk assessment using risk estimation matrix and factor screening studies employing Taguchi design aided in demarcating two critical method parameters, viz. mobile phase ratio and flow rate affecting critical analytical attributes. Subsequently, the optimum operational conditions of the liquid chromatographic method were delineated using face-centred composite design. Multicollinearity among the chosen factors for optimization was analyzed by the magnitude of variance inflation factor optimized analytical design space, providing optimum method performance, was earmarked using numerical and graphical optimization and corroborated using Monte Carlo simulations. Validation, as per the ICH Q2(R1) guidelines, ratified the efficiency and sensitivity of the developed novel analytical method of ferulic acid in the mobile phase and the human plasma matrix. The optimal method used a mobile phase, comprising of acetonitrile: water (47:53% v/v, pH adjusted to 3.0 with glacial acetic acid), at a flow rate of 0.8 mL·min-1, at a λmax of 322 nm using a C18 column. Use of principal component analysis unearthed the suitable wavelength for analysis, while analytical quality by design approach, along with Monte Carlo simulations, facilitated the identification of influential variables in obtaining the "best plausible" validated chromatographic solution for efficient quantification of ferulic acid.

Abstract
Abstract
The present studies describe the systematic development and validation of a simple, rapid, sensitive and cost-effective reversed-phase high-performance liquid chromatographic bioanalytical method for the estimation of valsartan in rat plasma employing analytical quality by design (AQbD) principles quality risk management was applied for identifying the critical method parameters (CMPs) and subsequently method optimization was performed employing Box–Behnken design by selecting mobile phase pH, flow rate and % organic modifier as the CMPs and evaluated for critical analytical attributes (CAAs) such as peak area, retention time, peak tailing and number of theoretical plates. The developed method was then transferred to bioanalysis, where liquid–liquid extraction process was used for separating the drug from rat plasma. The optimization of extraction process was performed with the help of face-centered cubic design by selecting centrifugation speed and centrifugation time as the CMPs for maximizing % recovery, signal-to-noise ratio and purity threshold of the drug peak after extraction as the CAAs. Optimum chromatographic solution was chosen by mathematical and graphical search techniques, and design space was demarcated. Validation studies performed for the developed method indicated linearity ranging between 5 and 100 ng.mL−1, whereas accuracy and precision study showed good percent recovery (99–102%) along with % relative standard deviation within ±2%. Sensitivity evaluation revealed limit of detection and limit of quantification were found to be 0.76 ng.mL−1 and 2.29 ng.mL−1, respectively. In a nutshell, the present work demonstrates significant merits of AQbD approach for holistic process understanding and analytical method development and validation with enhanced robustness and performance.

Abstract
Topical administration of corticosteroids is the cornerstone treatment of anterior uveitis, but poor corneal penetration and retention cause hindrance in their therapeutic utility. The conventional eye drops are less valuable in conditions where inflammation reaches deeper regions of the eye. Therefore, there is a clear need for an effective drug delivery system, which can increase corticosteroid penetration after topical application. To address this, cationic nanostructured lipid carriers of the drug triamcinolone acetonide (cTA-NLC) were prepared. The cTA-NLC were prepared by a hot microemulsion method and evaluated for drug release, permeation, cell uptake, cytotoxicity, anti-inflammatory activity and ocular irritancy. The cTA-NLC are nanometric in size (< 200 nm), with a zeta potential of about +35 mv and % drug EE of 88 %. The nanocarriers exhibited slow and sustained release of around 84 % in 24 h and transcorneal drug permeation of 51 % in 8 h. The nanocarriers exhibited no cytotoxicity (% cell viability of>90 %). The cell uptake study showed that nanocarriers could retain inside the cells for 24 h. The developed formulation could significantly reduce the TNF-α level in LPS induced inflamed cells. The studies indicated that cTA-NLC could be a promising option for the topical treatment of uveitis.

Abstract
The mainstay treatment of pulmonary disorders lies around the direct drug targeting to the lungs using a nebulizer, metered-dose inhaler, or dry powder inhaler. Only few inhalers are available in the market that could be used for inhalational drug delivery in rodents. However, the available rodent inhalers invariably require high cost and maintenance, which limits their use at laboratory scale. The present work, therefore, was undertaken to develop a simple, reliable, and cost-effective nose-only inhalation chamber with holding capacity of three mice at a time. The nebulized air passes directly and continuously from the central chamber to mouthpiece and maintains an aerosol cloud for rodents to inhale. Laser diffraction analysis indicated volume mean diameter of 4.02 ± 0.30 μm, and the next-generation impactor studies, however, revealed mean mass aerodynamic diameter of 3.40 ± 0.27 μm, respectively. An amount of 2.05 ± 0.20 mg of voriconazole (VRC) was available for inhalation at each delivery port of the inhaler. In vivo studies indicated the deposition of 76.12 ± 19.50 μg of VRC in the mice lungs when nebulized for a period of 20 min. Overall, the developed nose-only inhalation chamber offers a reliable means of generating aerosols and successfully exposing mice to nebulization.

Abstract
Background Psoriasis, a recurrent, chronic inflammatory disorder of skin, is a common problem in middle age and elderly people. Thymoquinone (TQ), a lipid soluble benzoquinone is the major active ingredient of volatile oil of Nigella sativa (NS), possesses good anti-psoriatic activity. However, its hydrophobicity, poor aqueous solubility, and photosensitive nature obstructs its development. Therefore, in the present research work, ethosomal vesicles (EVs) loaded with TQ were assessed for its anti-psoriatic potential employing mouse-tail model. Methods TQ-loaded EVs were prepared by cold method, and characterized for various essential attributes, viz. particle size, morphology, percent drug entrapment, flexibility, rheological and textural analysis, and skin absorption. The optimized formulation was finally evaluated for anti-psoriatic activity on Swiss albino mice employing mouse-tail model for psoriasis. Results The spherical shaped vesicles were in the nanosize range, and had high flexibility. The EVs incorporated hydrogel was rheologically acceptable and resulted in substantial TQ retention in the skin layers. The % anti-psoriatic drug activity was observed to be substantially better in the case of TQ-loaded ethosomal gel vis-à-vis plain TQ, NS extract, and marketed formulation. Conclusions The promising outcomes of the current studies ratify the superiority of TQ-loaded phospholipid-based vesicular systems for the management of psoriasis over other studied test formulations. This study, thus open promising avenues for topical application of TQ in the form of EV hydrogel.

Abstract
For a new immune modulator imiquimod, various liquid chromatography methods have been described in literature but all of them are deficient in one or other aspects of complete method development. The present work intends to develop and validate the stability indicating reverse phase high performance liquid chromatographic (HPLC) method. The isocratic flow of mobile phase comprising equal volume ratio of acetate buffer BP pH 3.7 and acetonitrile at the rate of 1.5 mL/min through the C-18 column at 25°C lead to elution of drug around 2.3 min when analyzed at 244 nm using UV-detector. The linear regression equation in calibration plot was y = 61632×-1224 with 0.9992 coefficient of determination (r2). The percent relative standard variation (% RSD) in peak area at low, mid and high region of linearity range was less than 5% in precision studies. The method was able to detect 0.039 μg/mL of drug but practical limit of quantitation (LOQ) was 1.5 μg/mL. The imiquimod molecule was stable in all except oxidizing conditions where it degraded into more polar molecule in hydrogen peroxide (H2O2) concentration dependent manner. Therefore, an analytical method capable of accurately and specifically estimating the drug in microgram range was successfully developed.

Abstract
INTRODUCTION Actinic keratosis is one of the most common disorder characterized by erythematic and generally attached scaly lesions which are present either alone or in clusters. World Health Organization defines actinic keratosis as a common intraepidermal neoplasm of sun-damaged skin, characterized by variable atypia of keratinocytes. AREAS COVERED At the beginning of the 20th century, a new immunomodulator molecule, imiquimod, appears in the market for the treatment of actinic keratosis but suffers from the pitfalls of the conventional approach of dosage form preparation including high dose, poor stability and more side effects. The present article attempts to compile the scatter information related to actinic keratosis and imiquimod at one place. The special emphasis will be made on the information available in various research articles and patents with respect to the efforts made for overcoming shortcomings associated with imiquimod by novel drug delivery or other approaches. EXPERT OPINION The conventional drug delivery systems are unsuccessful to improve the actinic keratosis. The patient acceptance and compliance with these treatments are generally poor due to associated side effects, poor cosmetic outcomes and high costs. Therefore, several available and reported novel therapeutic approaches are being developed in order to provide better action.

Abstract
The current studies envisage unravelling the underlying cellular internalisation mechanism of the systematically developed docetaxel (DTH) polyunsaturated fatty acid (PUFA) enriched self-nanoemulsifying lipidic micellar systems (SNELS). The concentration-, time- and cytotoxicity-related effects of DTH-SNELS on triple negative breast cancer (TNBC) MDA-MB-231 and non-TNBC MCF-7 cell lines were assessed through Presto-blue assay. Subsequently, rhodamine-123 (Rh-123) loaded SNELS were employed for evaluating their internalisation through flow cytometry and fluorescence microscopy, establishing it to be "clathrin-mediated" endocytic pathway. Apoptosis assay (65% cell death) and cell cycle distribution (47% inhibition at G2/M phase) further corroborated the cytotoxicity of DTH-SNELS towards cancerous cells. Biodistribution, histopathology and haematology studies indicated insignificant toxicity of the optimized formulation on vital organs. Preclinical anticancer efficacy studies using 7,12-dimethylbenzantracene (DMBA)-induced model construed significant reduction in breast tumor-volume. Overall, extensive in vitro and in vivo studies indicated the intracellular localization and cytotoxicity, suggesting DTH-SNELS as promising delivery systems for breast tumor therapeutics including TNBC.

Abstract
Our aim was to develop multiwalled carbon nanotubes (MWCNTs)-based nanoconstructs for the codelivery of N-desmethyl tamoxifen (N-TAM) and a mild P-gp efflux inhibitor, i.e., quercetin (QT) to treat multiple drug resistant (MDR) cancer cells. The hypothesis banks on three-tier attack on the MDR mechanisms viz. drug derivatization, MWCNT permeation and P-gp inhibition. Tamoxifen was converted to N-TAM and was conjugated to carboxylated MWCNTs mediated by a biodegradable linker, i.e., tetraethylene glycol (TEG). QT was adsorbed on the conjugate to fetch the final product, i.e., N-TAM-TEG-MWCNT-QT. Spectroscopic analysis confirmed successful conjugation of N-TAM and physical adsorption of QT. The in-vitro release of N-TAM from the N-TAM-TEG-MWCNT conjugate was minimal to that of pure drug under physiological conditions, but markedly enhanced under the acidic pH of cancer cells. The developed nanometeric formulation was found to be haemo-compatible. Reduced IC50values and better cellular uptake in drug resistant MDA-MB-231 cells were observed, followed by enhanced drug availability in the systemic circulation of rodents vis-à-vis naïve drug. The smart nanosystem conferred the desired temporal drug delivery, enhanced drug efficacy, biocompatibility and conducive pharmacokinetics, which are the crucial desired attributes to tackle the increasing concern of MDR in cancer chemotherapy.

Abstract
Beta carotene (βC) loaded nanoparticles of zein (βC-NPs) were developed using modified phase separation technique. βC-NPs were prepared using different zein concentration and optimized formulation was selected on the basis of micromeritics properties and entrapment efficiency. Further, βC-NPs were evaluated for in vitro release, in vitro cell-survival, cellular localization and apoptosis induced in MCF-7 cells. The combined effect of the βC and its nanoparticulate counterpart with MTX was evaluated thereafter for cytotoxicity and apoptotic activity in MCF-7 cells. In comparison to free βC, the βC-NPs demonstrated noteworthy improvement in various biopharmaceutical attributes viz Cmax (∼2.3-folds), AUCtotal (2.7-folds), t1/2 (∼1.5 folds) and MRT (∼1.5 folds), further indicating the remarkable increment in oral bioavailability of βC after incorporation in zein nanoparticles. The anti-tumour potential of prepared βC-NPs and effects of free βC and βC-NPs were investigated upon anticancer efficacy of methotrexate (MTX) in experimentally induced breast cancer rat model. Protective role of βC on MTX-associated hepatic toxicity in wistar rats was also determined using haematological and histopathological approaches. In a nutshell, zein nanoparticles improved the cellular uptake, cytotoxicity and exhibited enhanced oral biopharmaceutical performance of βC. This combination regimen could also be promising platform to facilitate the therapeutic benefits of anticancer agents.

Abstract
PURPOSE This research work entails quality by design (QbD)-based systematic development of nanostructured lipid carriers (NLCs) of Olmesartan medoxomil (OLM) with improved biopharmaceutical attributes. METHODS Quality target product profile (QTPP) was defined and critical quality attributes (CQAs) were earmarked. Solubility of drug was performed in various lipids for screening of them. NLCs were prepared by hot-microemulsion method using solid lipids, liquid lipids and surfactants with maximal solubility. Failure mode and effect analysis (FMEA) was carried out for identifying high risk formulation and process parameters. Further, principal component analysis (PCA) was applied on high risk parameters for evaluating the effect of type and concentration of lipids and surfactants on CQAs. Further, systematic optimization of critical material attributes (CMAs) was carried out using face centered cubic design and optimized formulation was identified in the design space. RESULTS FMEA and PCA suggested suitability of stearic acid, oleic acid and Tween 80 as the CMAs for NLCs. Response surface optimization helped in identifying the optimized NLC formulation with particle size ∼250 nm, zeta potential <25 mV, entrapment efficiency >75%, in vitro drug release >80% within 6 h. Release kinetic modeling indicated drug release through Fickian-diffusion mechanism. CONCLUSIONS Overall, these studies indicated successful development of NLCs using multivariate statistical approaches for improved product and process understanding.

Abstract
The aim of this study was to develop polyunsaturated fatty acid (PUFA) long chain glyceride (LCG) enriched self-nanoemulsifying lipidic nanomicelles systems (SNELS) for augmenting lymphatic uptake and enhancing oral bioavailability of docetaxel and compare its biopharmaceutical performance with a medium-chain fatty acid glyceride (MCG) SNELS. Equilibrium solubility and pseudo ternary phase studies facilitated the selection of suitable LCG and MCG. The critical material attributes (CMAs) and critical process parameters (CPPs) were earmarked using Placket-Burman Design (PBD) and Fractional Factorial Design (FFD) for LCG- and MCG-SNELS respectively, and nano micelles were subsequently optimized using I- and D-optimal designs. Desirability function unearthed the optimized SNELS with Temul <5min, Dnm <100nm, Rel15min >85% and Perm45min >75%. The SNELS demonstrated efficient biocompatibility and energy dependent cellular uptake, reduced P-gp efflux and increased permeability using bi-directional Caco-2 model. Optimal PUFA enriched LCG-SNELS exhibited distinctly superior permeability and absorption parameters during ex vivo permeation, in situ single pass intestinal perfusion, lymphatic uptake and in vivo pharmacokinetic studies over MCG-SNELS.

Abstract
Tamoxifen (TAM) is frequently prescribed for the management breast cancer, but is associated with the challenges like compromised aqueous solubility and poor bioavailability to the target site. It was envisioned to develop phospholipid-based mixed micelles to explore the promises offered by the biocompatible carriers. Various compositions were prepared, employing soya lecithin, polysorbate 80, sodium chloride/dextrose, and water, by self-assembled technique. The formulations were characterized for micromeritics and evaluated for in vitro drug release, hemolysis study, dermatokinetic studies on rodents, and cytotoxicity on MCF-7 cell lines. Cellular uptake of the system was also studied using confocal laser scanning microscopy. The selected composition was of sub-micron range (28.81 ± 2.1 nm), with spherical morphology. During in-vitro studies, the mixed micelles offered controlled drug release than that of conventional gel. Cytotoxicity was significantly enhanced and IC50 value was reduced that of the naïve drug. The bioavailability in epidermis and dermis skin layers was enhanced approx. fivefold and threefold, respectively. The developed nanosystem not only enhanced the efficacy of the drug but also maintained the integrity of skin, as revealed by histological studies. The developed TAM-nanocarrier possesses potential promises for safe and better delivery of TAM.

Abstract
Various preclinical/clinical studies support the effectiveness of ketoprofen in periodontitis; however, the literature reveals that novel delivery systems have been less explored for the drug in periodontitis. The current investigation aims to explore the potential of a pro-vesicular approach-based proniosomal drug delivery of ketoprofen for its effectiveness and validation in experimental periodontal disease (EPD). Formulations were developed using I-optimal mixture design. Developed formulations were characterized for entrapment efficiency, vesicle size, and in vitro drug release. Selected proniosomal gels were evaluated for mucoadhesiveness, ex vivo drug permeation, and retention studies. Optimized proniosomal gel was evaluated for surface morphology, rheological behavior, texture studies, and pharmacodynamic activity in EPD. The results showed that ketoprofen-loaded proniosomal formulations formed a mucoadhesive hydrogel comprising spherical and flexible vesicles. Viscosity and texture studies showed good adhesion and smoothness, which are desired for enhanced permeation. The disease condition was improved with preserved bone resorption process, that too with intact cementum vis-à-vis marketed gel formulation, when evaluated in the EPD model. The results lead to the conclusion that proniosomes can act as a promising carrier and can be effectively used for improved ketoprofen delivery in periodontal pockets.

Abstract
Various oral treatment options have been reported for relapsing multiple sclerosis. Recently, dimethyl fumarate (DMF) has been approved for the management of the same. Though effective, DMF is associated with concerns like multiple dosing, patient incompliance, gastrointestinal flushing, lower brain permeation, and economic hurdles. Henceforth, the objective of the present study was to develop vitamin-based solid lipid nanoparticles (SLNs) for effective brain delivery of DMF with a promise of once-a-day dosing. The developed SLNs were characterized for micromeritics, morphology, entrapment efficiency, drug loading and in vitro drug release. Caco-2 and SH-SY5Y cell lines were used to assess the intestinal permeability and neuronal uptake. Pharmacokinetic and biodistribution studies were performed on rats. The developed nanometeric lipidparticles were able to control the drug release and substantially enhance the Caco-2 as well as SH-5YSY cell permeability. The developed systems not only enhanced the oral bioavailability of the drug, but also offered substantially elevated brain drug levels to that of plain drug. The drug was protected from liver and biological residence was increased, indicating promising potential of the carriers in effective brain delivery of DMF. Enhanced bioavailability and elevated bioresidence of DMF by vitamin-based SLNs provided the evidence for once-a-day delivery potential for DMF in the management of neurological disorders.

Abstract
IMPORTANCE Attempts to use topical cyclosporine in treatment of psoriasis have failed because of unfavorable physicochemical properties and inappropriate formulation design of the conventional dosage forms. OBJECTIVE To evaluate the efficacy of topical cyclosporine using liposomal nanocarriers (lipogel) in limited chronic plaque psoriasis. DESIGN, SETTING, AND, PARTICIPANTS A single-center randomized clinical trial was conducted using a 3-arm parallel group, double-blind, vehicle and active comparator design and included 38 patients with chronic plaque psoriasis measuring less than or equal to 100 cm2 performed in a tertiary care hospital. INTERVENTIONS In the first arm, a total of 24 patients were randomized to receive either cyclosporine lipogel, 2.0% weight by weight (w/w), or placebo lipogel. In the second arm, 7 patients were randomized to receive cyclosporine lipogel, 2.0%, or conventional cyclosporine cream, 2.0% w/w. The third arm comprised 7 patients randomized with cyclosporine lipogel, 2.0% or standard clobetasol propionate cream, 0.05% w/w. Patients were examined twice weekly for 14 weeks, or until total lesional clearance was observed, whichever was earlier. MAIN OUTCOMES AND MEASURES The primary outcome measure was the dermatological sum score (DSS) assessing erythema, scaling, and plaque elevation on a 4-point scale (0, absent; 1, minimal; 2, moderate; 3, severe). RESULTS In 38 patients (23 men and 15 women with a mean [SD] age range from 35 [8] to 40 [13] years), a 19% decrease in DSS score from a mean (SD) of 8.45 (0.67) to 6.82 (0.77) compared with baseline was observed after 2 weeks of treatment with cyclosporine lipogel, 2.0% w/w (P < .001; 95% CI, 13.77-24.51) in 59% of psoriasis lesional sites. At the end of the eighth week, a significant reduction (approximately 83%) in DSS was seen in all sites treated with cyclosporine lipogel, (P < .001; 95% CI, 77.48-88.22). At the end of the study period, complete clearance (ie, DSS = 0) was observed in 16 (41%) psoriasis lesional sites treated with cyclosporine lipogel, 85.7% of sites treated with clobetasol propionate cream, and none of the sites treated with conventional cyclosporine cream or placebo gel. CONCLUSIONS AND RELEVANCE Topical liposomal formulation of cyclosporine, 2.0% w/w, is effective in treatment of limited chronic plaque psoriasis with a satisfactory safety profile. Future clinical trials should assess liposomal cyclosporine in larger study populations. TRIAL REGISTRATION Clinical Trials Registry-India Identifier: CTRI/2011/12/002307.

Abstract
The present study was aimed to coencapsulate methotrexate (MTX) and aceclofenac (ACL) in fucose anchored lipid-polymer hybrid nanoparticles (Fu-LPHNPs) to achieve target specific and controlled delivery for developing therapeutic interventions against breast cancer. The effective combination therapy requires coadministration of drugs to achieve synergistic effect on tumor with minimum adverse effects. Present study investigates the potential of codelivery of MTX and ACL through LPHNPs in MCF-7 and triple negative breast cancer cells (MDA-MB-231). We obtained LPHNPs in the nanosize range (<150 nm) with better particle size distribution (<0.3). The entrapment and loading efficiency of MTX and ACL was calculated as 85-90% and 10-12%, respectively. The coumarin-6 LPHNP formulations showed rapid internalization within 2 h incubation with MCF-7 and MDA-MB-231 cells. With 8-10 times, greater bioavailability of drug-loaded LPHNPs than free MTX and ACL was obtained. Also, antitumor efficacy of MTX- and ACL-loaded LPHNPs was determined on DMBA-induced experimental breast cancer mouse model. This model showed better control over tumor growth with MTX- and ACL-loaded LPHNPs than the combination of MTX and ACL or MTX alone. ACL-loaded LPHNPs showed prophylactic and anticancer activity in DMBA-induced mouse model at higher dose (10 mg/kg). ACL-LPHNPs confer synergistic anticancer effect when administered in combination with MTX. In conclusion, ACL enhances the therapeutic and anticancer efficacy of MTX, when coencapsulated into fucose-anchored LPHNPs, as confirmed by cell viability and serum angiogenesis (IL-6, TNF-α, IL-1β, COX2, and MMP1) at both transcript and proteome level.

Abstract
Dimethyl fumarate (DMF) is an approved drug for the management of relapsing multiple sclerosis. Despite efficacy, DMF is also reported to be a challenging drug owing to concerns like gastrointestinal tract flushing, multiple dosing, lower brain permeability, less patient compliance, and economic hurdles. The present study aims to develop DMF-tocopherol acetate nanolipidic carrier (NLCs) to enhance brain permeability and improve the gastric tolerance. The developed DMF-tocopherol acetate NLCs offered an average size of 69.70 nm, PDI of 0.317, and a zeta potential of -9.71 mV. Higher drug entrapment (90.12%) and drug loading (20.13%) assured controlled drug release behavior both in gastric and intestinal pH. Cellular uptake studies on Caco-2 and SH-SY5Y monolayers confirmed better intestinal absorption and neuronal uptake of the developed system, which was further corroborated by the pharmacokinetic and biodistribution studies. The oral bioavailability was enhanced by 4.09 times and brain availability was substantially improved vis-à-vis plain drug. The findings are promising and offer preclinical evidence for better brain availability of DMF, which can be exploited in the better management of diseases like multiple sclerosis.

Abstract
The topical delivery of local anaesthetics has always been a difficult task due to the limited percutaneous absorption of local anaesthetic drugs across the various barriers of the skin. In this pursuit, a thermoresponsive mixed micellar nanogel (MMNG) system of lidocaine and prilocaine has been attempted in the current piece of work. The system relies on the ability to alter its phase state (sol-to-gel) for feasibility of the topical application in response to change in temperature. The composition of MMNG entails majorly of Pluronic® F127 and Tween 80 in a fixed combination so as to provide the desired thermoreversibility for the skin application. The gels were optimized with respect to phase transition temperature (T sol/gel), turbidity and viscosity. The optimized systems were then characterized for particle size, spreadability, syringeability, bioadhesive strength, ex vivo skin permeation, retention and dermatokinetic studies. The skin compatibility revealed that no histological changes were observed for optimized formulation, while the conventional system showed changes in the skin-tissues. Further, the enhanced intensity of anaesthetic effect was noted in an in vivo rabbit model and tail flick model in mice. The overall results suggest that the prepared MMNG system possesses the potential in providing an efficacious, safe and acceptable alternative therapeutic system for topical anaesthesia.

Abstract
Water dispersible fullerenes were synthesized by tethering with glycine. The glycinated fullerenes were conjugated to docetaxel and characterized using FT-IR and NMR. The nanometric drug-loaded carriers were able to release drug at cancer cell pH, but resisted drug release at plasma pH. The cytotoxicity in MDA MB-231 cells was substantially enhanced as well as the system was well tolerated by erythrocytes. The confocal laser scanning microphotographs confirmed the substantial drug delivery to cytosol as well as nuclei of cancer cells. The developed system not only increased the circulation time of drug, but also decreased its protein binding and substantially enhanced AUC. The glycinated fullerenes can serve as promising "cargo vehicles" for delivery of anti-cancer drugs in safe and effective manner.

Abstract
There are several significant setbacks including limited bioavailability, high clearance, and further current therapies require higher and frequent dosing to gain desired therapeutic effects. Nanomedicines have been widely investigated for rheumatoid arthritis (RA). Though, higher doses also increase the incidence of dreadful adverse effects. Further, nanocarrier properties are tuned by the use of different approaches like varied methods of loading, hydrophilic polymers and targeting ligands, to change the physicochemical properties including higher encapsulation, better penetrating ability to biological barriers, thus preventing the uptake of various nanocarriers by liver and spleen. Along with these they provide longer circulation which enhances drug localization at the inflamed site and selective targeting to enhance the therapeutic index of anti-rheumatic drugs. However, the optimal properties also depend on the route of administration and nanocarrier size, thus larger size show more retention upon local injection and smaller sized ones are more optimal for passive targeting. The present review discusses the emergence of nano-carriers for anti-rheumatic drugs, which delivers drug molecule to the inflamed site by topical, intra-articular (i.a) and intra-venous (i.v) administration to achieve therapeutic efficacy by passive and active drug targeting. Advancements have been made extensively but still better investigations are needed to optimize the risk-benefit ratio for the development of safe and stable targeting nanocarriers for the effective treatment of rheumatoid arthritis (RA).

Abstract
Present study was designed to prepare and characterize aceclofenac loaded nanostructured lipid carriers (NLCs) employing Quality by Design (QbD)-oriented approach. The NLCs were evaluated for their transdermal penetration potential and stability. Aceclofenac loaded nanostructured lipid carriers (NLCs) were prepared & characterized, by employing Quality by Design (QbD)-oriented approach and further evaluated for transdermal penetration potential and stability. Different lipids and surfactants were chosen to prepare NLCs using microemulsion method as critical material attributes (CMAs). A 33 factorial design was used for optimization of NLCs, and evaluating them for different critical quality attributes (CQAs), viz. particle size, polydispersity index (PDI), zeta potential, in vitro drug release, entrapment efficiency. The effect of CMAs such as lipids, oil: lipid ratio and concentration of surfactants on CQAs viz. drug entrapment efficiency and particle size were systematically evaluated to optimize NLCs. The optimized NLCs were further incorporated into carbopol gel and characterized for texture and rheology profile followed by in vitro and in vivo evaluations. The optimized ACE-NLCs were found to be spherical, nanometric in size with higher drug loading and entrapment efficiency. Results of the in vitro drug release study showed that the developed formulation followed Korsmeyer-Peppas model showing Fickian diffusion. The release was biphasic i.e., initial burst release followed by sustained drug release upto 48h. The optimized NLCs-based gel formulation showed superior texture, rheological profile and showed better cell uptake efficiency on hyperkeratinocytic cells (HaCaT cell lines) with higher ex vivo skin permeability efficiency vis-à-vis marketed formulation. In conclusion, dermatokinetic modeling and pharmacodynamic study using carrageenan induced edema mice suggests that aceclofenac loaded NLCs hydrogel may provide a better delivery alternative to target various skin layers.

Abstract
The present work endeavors for development and evaluation of resveratrol loaded niosomal hydrogel system for its anti-inflammatory action. Niosomes were prepared by thin film hydration and ether injection methods employing Span 80 as a surfactant at three different levels. Best optimized formulation was selected on the basis of entrapment efficiency (% EE), mean particle size, sedimentation volume, and microscopy. The vesicular and spherical nature of the niosomes was confirmed by optical microscopy and transmission electron microscope (TEM). Further, resveratrol entrapped niosomal gel was prepared by gelling in Carbopol 934, and evaluated for pH, viscosity, and in vitro release, employing dialysis membrane method. The in vitro release data after fitting to various models revealed it to follow Korsmeyer-Pappas model. Ex vivo permeation studies witnessed high permeation and deposition of resveratrol in skin when compared to plain resveratrol. Dermatokinetic studies elaborated that niosomal gel enhanced the biological half-life and reduced Tmax of the drug, in both the skin layers. Finally, in vivo anti-inflammatory activity of niosomal gel was evaluated by carrageenan induced paw edema model and compared with standard sodium diclofenac gel. The resveratrol entrapped niosomal gel sufficiently reduced the edema and revealed prolonged therapeutic action vis-a-vis the marketed anti-inflammatory gel formulation. Our findings suggest that a topical drug delivery system using niosomal hydrogel could lead to expansion in the anti-inflammatory use of resveratrol.

Abstract
AIM The present studies describe Quality by Design-oriented development and characterization of surface-engineered solid lipid nanoparticles (SLNs) of rosuvastatin calcium for low density lipoprotein-receptor targeting. MATERIALS & METHODS SLNs were systematically prepared employing Compritol 888 and Tween-80. Surface modification of SLNs was accomplished with Phospholipon 90G and DSPE-mPEG-2000 as the ligands for specific targeting to the low density lipoprotein-receptors. SLNs were evaluated for size, potential, entrapment, drug release performance and gastric stability. Also, the formulations were evaluated for cellular cytotoxicity, uptake and permeability, pharmacokinetic, pharmacodynamic and biochemical studies. RESULTS & CONCLUSION Overall, the studies ratified enhanced biopharmaceutical performance of the surface-engineered SLNs of rosuvastatin as a novel approach for the management of hyperlipidemia-like conditions.

Abstract
The objectives of the present studies were to develop the systematically optimized selfnanoemulsifying drug delivery systems (SNEDDS) of valsartan employing the holistic QbD approach. The quality profile target product (QTPP) was defined and critical quality attributes (CQAs) earmarked. Preformulation studies including the equilibrium solubility and pseudoternary phase titration studies facilitated the selection of suitable lipids and emulgents for formulation of SNEDDS. Risk assessment and factor screening studies facilitated the selection of Lauroglycol FCC and Capmul MCM L8 (i.e., lipid), Tween 40 and Tween 80 (i.e., emulgent) as the critical material attributes (CMAs) for SNEDDS prepared using medium-chain triglycerides (MCTs) and long-chain triglycerides (LCTs). A central composite design (CCD) was employed for systematic optimization of SNEDDS, taking globule size (Dnm), drug release in 10 min (Q10min) and amount permeated in 45 min (%Perm45min) as the CQAs. Design space was generated using apt mathematical models to embark upon the optimized formulations and validation of the QbD. In situ SPIP studies revealed significant improvement in the absorptivity and permeability parameters of SNEDDS owing to the inhibition of P-gp/MRP2 efflux vis-à-vis the conventional marketed formulation and pure drug. In vivo pharmacokinetic studies corroborated marked enhancement in the oral bioavailability drug from SNEDDS vis-à-vis the marketed formulation. Establishment of various levels of in vitro/in vivo correlations (IVIVC) indicated excellent goodness of fit between the in vitro drug release data with the in vivo absorption parameters. In a nutshell, the present studies report successful QbD-based development of MCT and LCT-SNEDDS of valsartan with improved biopharmaceutical performance.

Abstract
Benzyl benzoate (BB) is one of the oldest drugs used for the treatment of scabies and is recommended as the "first-line intervention" for the cost-effective treatment of the disease. Though a promising candidate, its application is reported to be associated with irritation of the skin and eye, resulting in poor patient compliance. Hence, the present study aims to develop BB-loaded topical microemulsion for the safer and effective delivery of BB. Pseudo-ternary phase diagrams with BB as the oily phase itself, along with Tween 80 as surfactant, and mixture of phospholipid and ethanol as the co-surfactant along with aqueous solution as the external phase were constructed and various compositions were formulated. The optimized formulation was characterized for particle-size, zeta-potential, drug-content, globule-morphology pH, and refractive-index, whereas evaluated for skin permeation, retention, compliance, and dermatokinetics. The nanosized formulation offered threefold higher drug permeation vis-a-vis plain drug solution across LACA mice abdominal skin. The drug retention of the selected formulation was nearly twice of that from the marketed product, assuring depot formulation and sustained release. The skin histopathology revealed the non-irritant nature of the formulation, as no changes in the normal skin histology were observed. The dermatokinetic studies confirmed better permeation and enhanced skin bioavailability of BB to epidermis as well as dermis vis-à-vis the conventional product. The results indicate that the developed lipid-based microemulsion hydrogel can alleviate the concerns associated with BB and can provide a better and safer delivery option in substantial amounts to various skin layers.

Abstract
Carbon nanotubes (CNTs), owing to their inherently unique properties in the domain of biomedical sciences including drug delivery, offer an exciting platform to the researchers. Of late, their applications have also been successfully established. Recently, single-walled CNTs (SWCNTs) have been explored for antibacterial efficacy, but naïve multi-walled CNTs (MWCNTs) still remained unearthed. The present studies endeavor the investigation of the potential of various non-ionic surfactants in solubility enhancement of MWCNTs and their subsequent antibacterial efficacy against Escherichia coli and Staphylococcus aureus. Polysorbates offer more solubility to MWCNTs vis-à-vis the phospholipids. However, the antibacterial effect was found to be less influenced by solubility but significantly determined by the type of surfactant. Transmission electron photomicrographs confirmed significant adhesion of MWCNTs to the bacterial walls only in the presence of unsaturated phospholipids and this was expressed in the form of lowest minimum inhibitory concentration (MIC) values of MWCNTs dispersed with the same. The findings are unique as MWCNTs were found to be active against both Gram-negative and Gram-positive bacteria to a similar extent, though somewhat milder than SWCNTs. However, when dispersed with unsaturated phospholipids, the former offer almost comparable antibacterial effects to that of the latter. The study opens a new research domain to further explore the antibacterial effects of non-functionalized and relatively safer MWCNTs, accentuating the importance of biocomponents like unsaturated phospholipids in this purview.
