Abstract
Microfluidics has emerged as a transformative force in the field of drug delivery, offering innovative avenues to produce a diverse range of nano drug delivery systems. Thanks to its precise manipulation of small fluid volumes and its exceptional command over the physicochemical characteristics of nanoparticles, this technology is notably able to enhance the pharmacokinetics of drugs. It has initiated a revolutionary phase in the domain of drug delivery, presenting a multitude of compelling advantages when it comes to developing nanocarriers tailored for the delivery of poorly soluble medications. These advantages represent a substantial departure from conventional drug delivery methodologies, marking a paradigm shift in pharmaceutical research and development. Furthermore, microfluidic platformsmay be strategically devised to facilitate targeted drug delivery with the objective of enhancing the localized bioavailability of pharmaceutical substances. In this paper, we have comprehensively investigated a range of significant microfluidic techniques used in the production of nanoscale drug delivery systems. This comprehensive review can serve as a valuable reference and offer insightful guidance for the development and optimization of numerous microfluidics-fabricated nanocarriers.

Abstract
In this study, the new solid lipid nanoparticles were created by combining fluorescent dye, fatty acid, lipid, and bacterial outer membranes. The synthesised particles were roughly 95-100 nm in size. Vero cells cultivated with these nanoparticles showed no cytotoxicity in 5-dimethylthiazol-2-yl-2, 5-diphenyltetrazolium bromide (MTT) assay. In the cell uptake studies, the vero cell line was employed. Cell lines absorbed fluorescent solid lipid nanoparticles (FSL NPs) better, according to the findings. The confocal microscopy results revealed a significant accumulation of FSL NPs in the cytoplasm over time. The results of small animal imaging employing BALB/c mice revealed that the nanoparticles generated provided high contrast signals. Overall, the OMVs-based FSL NPs system offers a unique imaging tool for studying intracellular interactions as well as a viable tool for drug delivery.

Abstract
Nanoparticle systems are functional carriers that can be used in the cancer therapy field for the delivery of a variety of hydrophobic and/or hydrophilic drugs. Recently, the advent of microfluidic platforms represents an advanced approach to the development of new nanoparticle-based drug delivery systems. Particularly, microfluidics can simplify the design of new nanoparticle-based systems with tunable physicochemical properties such as size, size distribution and morphology, ensuring high batch-to-batch reproducibility and consequently, an enhanced therapeutic effect in vitro and in vivo. In this perspective, we present accurate state-of-the-art microfluidic platforms focusing on the fabrication of polymer-based, lipid-based, lipid/polymer-based, inorganic-based and metal-based nanoparticles for biomedical applications.

Abstract
In conventional drug administration, drug molecules cross multiple biological barriers, distribute randomly in the tissues, and can release insufficient concentrations at the desired pathological site. Controlling the delivery of the molecules can increase the concentration of the drug in the desired location, leading to improved efficacy, and reducing the unwanted effects of the molecules under investigation. Nanoparticles (NPs), have shown a distinctive potential in targeting drugs due to their unique properties, such as large surface area and quantum properties. A variety of NPs have been used over the years for the encapsulation of different drugs and biologics, acting as drug carriers, including lipid-based and polymeric NPs. Applying NP platforms in medicines significantly improves the disease diagnosis and therapy. Several conventional methods have been used for the manufacturing of drug loaded NPs, with conventional manufacturing methods having several limitations, leading to multiple drawbacks, including NPs with large particle size and broad size distribution (high polydispersity index), besides the unreproducible formulation and high batch-to-batch variability. Therefore, new methods such as microfluidics (MFs) need to be investigated more thoroughly. MFs, is a novel manufacturing method that uses microchannels to produce a size-controlled and monodispersed NP formulation. In this review, different formulation methods of polymeric and lipid-based NPs will be discussed, emphasizing the different manufacturing methods and their advantages and limitations and how microfluidics has the capacity to overcome these limitations and improve the role of NPs as an effective drug delivery system.

Abstract
The blood-brain barrier (BBB) plays a vital role in the protection and maintenance of homeostasis in the brain. In this way, it is an interesting target as an interface for various types of drug delivery, specifically in the context of the treatment of several neuropathological conditions where the therapeutic agents cannot cross the BBB. Drug toxicity and on-target specificity are among some of the limitations associated with current neurotherapeutics. In recent years, advances in nanodrug delivery have enabled the carrier system containing the active therapeutic drug to target the signaling pathways and pathophysiology that are closely linked to central nervous system (CNS) disorders such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), multiple sclerosis (MS), brain tumor, epilepsy, ischemic stroke, and neurodegeneration. At present, among the nano formulations, solid lipid nanoparticles (SLNs) have emerged as a putative drug carrier system that can deliver the active therapeutics (drug-loaded SLNs) across the BBB at the target site of the brain, offering a novel approach with controlled drug delivery, longer circulation time, target specificity, and higher efficacy, and more importantly, reducing toxicity in a biomimetic way. This paper highlights the synthesis and application of SLNs as a novel nontoxic formulation strategy to carry CNS drugs across the BBB to improve the use of therapeutics agents in treating major neurological disorders in future clinics.

Abstract
Phenolic compounds are one of the most widespread classes of compounds in nature, with several beneficial biological effects being associated with their anti-oxidant and anti-carcinogenic activities. Their application in the prevention or treatment of numerous chronic diseases have been studied, but a major drawback is still the low bioavailability of these compounds, as well as their instability towards pH, temperature, and light in some cases. Nanotechnology has emerged as an alternative to overcome these limitations, and the use of lipidic encapsulation systems is a promising technique to achieve an efficient drug delivery, protecting molecules from external factors and improving their bioavailability. In this review, solid lipid nanoparticles and nanostructured lipid carriers are highlighted as an important tool for the improvement of the bioavailability and stability of natural phenolic compounds, including their preparation methods and functionalization approaches and the discussion of several applications for putative use in cosmetic and pharmacologic products.

Abstract
Nanoparticle albumin-bound (nab)-technology is an industrial applicable manufacturing method for the preparation of albumin-based drug carriers of poorly water-soluble drugs. In the present study the advantages of nanotechnology, albumin as an endogenous protein with the capability of high tumor enrichment and the selective light activation of the photosensitizer Temoporfin (mTHPC) were combined to a new delivery system for oncological use. The herewith provided well-established photodynamic therapy may enable a beneficial alternative for the treatment of solid tumors. In the present study a reproducible method for the preparation of stable mTHPC-albumin nanoparticles via nab-technology was established. The nanoparticles were physicochemically characterized with regard to particle size and size distribution and the impact of this preparation method on nanoparticle as well as mTHPC stability was investigated. Nanoparticles with improved colloidal stability over a broad pH range and in the presence of physiological NaCl concentrations were achieved in high yield. Due to high pressure homogenization a certain oxidative decay of mTHPC was observed. Cell culture experiments revealed an effective cellular uptake of mTHPC in a cholangiocarcinoma cell line (TFK-1). After light-activation high cytotoxicity was shown for photosensitizer loaded nanoparticles enabling the application of the proposed formulation in photodynamic therapy.

Abstract
Unlike conventional emulsions, solid lipids are used to prepare solid lipid nanoparticles (SLNs) with crystalline structures and nanostructured lipid carriers (NLCs) with imperfect crystals or amorphous structures to encapsulate various bioactive compounds significant to food applications. The solid lipid matrix can stabilize particle structures and control release properties of the encapsulated compounds that may not be possible for emulsions with liquid droplets. In this review, common approaches of preparing SLNs and NLCs are first presented, followed by parameters used to study lipid particles, including dimensional, morphological, charge, thermal, and crystalline properties. The structures of SLNs and NLCs with respect to the release mechanisms of encapsulated compounds are discussed in the context of lipid and emulsifier chemistry and preparation conditions. Lastly, possible applications of SLNs and NLCs in food systems are discussed.

Abstract
Apigenin has attracted a great interest in the food industry due to the wide range of its biological activities including antioxidant and anti-inflammatory. The encapsulation of apigenin in oil-in-water (O/W) emulsions could overcome its low solubility and lead to the development of new functional food products. The aim of this study is to formulate food-grade O/W submicron emulsions loaded with apigenin using high-pressure homogenization. Supersaturated solutions of 0.1 wt% apigenin in ethyl oleate were heated at 100 °C for 30, 60, or 120 min and the supernant after centrifugation were used as to-be-dispersed phases. An aqueous solution containing 1 wt% tween 20 was used as the continuous phase. We examined the effect of heating process of the ethyl oleate prior to emulsification and the homogenization-pressure (60-150 MPa) on the physico-chemical characteristics of the O/W emulsions immediately after formulation and during storage. Submicron O/W emulsions were formulated and the lowest average droplet diameter (dav) was 169 ± 2.082 nm with a polydispersity index (PDI) of 0.06 ± 0.002. After 30 days of storage at 4 °C, the O/W emulsion formulated remained physically stable with little change in their dav and PDI values. The preheat treatment of ethyl oleate, affected the initial loaded apigenin concentration but hardly affected the physico-chemical stability of O/W emulsions. However, HPLC analysis demonstrated that the emulsification pressure was a relevant parameter affecting apigenin retention during the storage of O/W emulsions. Apigenin degradation in ethyl oleate O/W emulsions followed zero order kinetics and about 91.5-93.5% of apigenin could be retained in O/W emulsions after 30 days of storage.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (IBP) are among the most prescribed drugs across the globe. However, most NSAIDs are insoluble in water leading them to have poor bioavailability and erratic absorption. Moreover, NSAIDs such as IBP and ketoprofen (KP) have to be administered very frequently due to their short plasma half-life leading to side effects. Controlled release formulations of IBP, KP and nabumetone (NBT) based on solid lipid nanoparticles (SLNs) were successfully synthesised in the present study to solve the above-mentioned challenges that are associated with NSAIDs. SLNs were prepared in two steps; hot-melt homogenization followed by sonication to formulate SLNs with spherical morphology. While capmul® GMS-50K (capmul) was used as the lipid due to the high solubility of the studied drugs in it, gelucire® 50/13 (gelucire) was used as the surfactant. It was found that particle size was directly proportional to drug concentration and inversely proportional to surfactant concentration, volume of water added and temperature of water. Ultrasonication in a pulse mode with optimum duration of 15min was essential to obtain smaller nanoparticles through the formation of a nanoemulsion. Drug loaded SLNs with small particle size and narrow size distribution with good solid loading, encapsulation efficiency and drug loading percentage could be prepared using the optimised conditions. SLNs prepared at the optimised condition were characterized thoroughly by using different techniques such as dynamic light scattering (DLS), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), X-ray diffraction (XRD), differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR). The cytotoxicity results showed that the prepared SLNs are non-toxic to Raw cell line. The drugs IBP, KP and NBT showed 53, 74 and 69% of percentage entrapment efficiency with drug loading of 6, 2 and 7% respectively. Slow, steady and sustained drug release was observed from the SLNs for over 6days.

Abstract
Proteins are a vital constituent of the body as they perform many of its major physiological and biological processes. Recently, proteins and peptides have attracted much attention as potential treatments for various dangerous and traditionally incurable diseases such as cancer, AIDS, dwarfism and autoimmune disorders. Furthermore, proteins could be used for diagnostics. At present, most therapeutic proteins are administered via parenteral routes that have many drawbacks, for example, they are painful, expensive and may cause toxicity. Finding more effective, easier and safer alternative routes for administering proteins and peptides is the key to therapeutic and commercial success. In this context, much research has been focused on non-invasive routes such as nasal, pulmonary, oral, ocular, and rectal for administering proteins and peptides. Unfortunately, the widespread use of proteins and peptides as drugs is still faced by many obstacles such as low bioavailability, short half-life in the blood stream, in vivo instability and numerous other problems. In order to overcome these hurdled and improve protein/peptide drug efficacy, various strategies have been developed such as permeability enhancement, enzyme inhibition, protein structure modification and protection by encapsulation. This review provides a detailed description of all the previous points in order to highlight the importance and potential of proteins and peptides as drugs.

Abstract
BACKGROUND The emulsification-evaporation method was used to prepare astaxanthin nanodispersions using a three-component emulsifier system composed of Tween 20, sodium caseinate and gum Arabic. Using Response-surface methodology (RSM), we studied the main and interaction effects of the major emulsion components, namely, astaxanthin concentration (0.02-0.38 wt %, x1), emulsifier concentration (0.2-3.8 wt %, x2) and organic phase (dichloromethane) concentration (2-38 wt %, x3) on nanodispersion characteristics. The physicochemical properties considered as response variables were: average particle size (Y1), PDI (Y2) and astaxanthin loss (Y3). RESULTS The results indicated that the response-surface models were significantly (p < 0.05) fitted for all studied response variables. The fitted polynomial regression models for the prediction of variations in the response variables showed high coefficients of determination (R2 > 0.930) for all responses. The overall optimum region resulted in a desirable astaxanthin nanodispersions obtained with the concentrations of 0.08 wt % astaxanthin, 2.5 wt % emulsifier and 11.5 wt % organic phase. CONCLUSION No significant differences were found between the experimental and predicted values, thus certifying the adequacy of the Response-surface models developed for describing the changes in physicochemical properties as a function of main emulsion component concentrations.

Abstract
Nanostructured lipid carriers (NLC) composed of solid and liquid lipids, and surfactants are potentially good colloidal drug carriers. Before NLC can be used as drug carriers, the cytotoxicity of their components must be ascertained. The cytotoxicity of solid lipids (trilaurin, palmitin, docosanoid acid, and hydrogenated palm oil [HPO]) and surfactants (Polysorbate 20, 80, and 85) were determined on BALB/c 3T3 cells. The HPO and Polysorbate 80 were least cytotoxic and used with olive oil in the formulation of NLC. The particle size, polydispersity index, zeta potential, specific surface area, and crystallinity index of the NLC were 61.14 nm, 0.461, -25.4 mV, and 49.07 m(2) and 27.12% respectively, while the melting point was 4.3 °C lower than of HPO. Unlike in serum-free, NLC incubated in fetal bovine serum-supplemented medium did not show particle growth, suggesting that serum proteins in medium inhibit nanoparticles aggregation. The study also showed that NLC was less toxic to BALB/c 3T3 cells than Polysorbate 80. Thus, NLC with olive oil, HPO, and Polysorbate 80 as components are potentially good drug carriers with minimal cytotoxicity on normal cells.

Abstract
A simplex centroid mixture design was used to study the interactions between two chosen solvents, dichloromethane (DCM) and acetone (ACT), as organic-phase components in the formation and physicochemical characterization and cellular uptake of astaxanthin nanodispersions produced using precipitation and condensation processes. Full cubic or quadratic regression models with acceptable determination coefficients were obtained for all of the studied responses. Multiple-response optimization predicted that the organic phase with 38% (w/w) DCM and 62% (w/w) ACT yielded astaxanthin nanodispersions with the minimum particle size (106 nm), polydispersity index (0.191), and total astaxanthin loss (12.7%, w/w) and the maximum cellular uptake (2981 fmol/cell). Astaxanthin cellular uptake from the produced nanodispersions also showed a good correlation with their particle size distributions and astaxanthin trans/cis isomerization ratios. The absence of significant (p > 0.05) differences between the experimental and predicted values of the response variables confirmed the adequacy of the fitted models.

Abstract
Solid lipid nanoparticles are at the forefront of the rapidly developing field of nanotechnology with several potential applications in drug delivery, clinical medicine and research, as well as in other varied sciences. Due to their unique size-dependent properties, lipid nanoparticles offer the possibility to develop new therapeutics. The ability to incorporate drugs into nanocarriers offers a new prototype in drug delivery that could be used for secondary and tertiary levels of drug targeting. Hence, solid lipid nanoparticles hold great promise for reaching the goal of controlled and site specific drug delivery and hence have attracted wide attention of researchers. This review presents a broad treatment of solid lipid nanoparticles discussing their advantages, limitations and their possible remedies. The different types of nanocarriers which were based on solid lipid like solid lipid nanoparticles, nanostructured lipid carriers, lipid drug conjugates are discussed with their structural differences. Different production methods which are suitable for large scale production and applications of solid lipid nanoparticles are described. Appropriate analytical techniques for characterization of solid lipid nanoparticles like photon correlation spectroscopy, scanning electron microscopy, differential scanning calorimetry are highlighted. Aspects of solid lipid nanoparticles route of administration and their biodistribution are also incorporated. If appropriately investigated, solid lipid nanoparticles may open new vistas in therapy of complex diseases.

Abstract
In the pharmaceutical, cosmetic, chemical, and food industries high-pressure homogenization is used for the preparation or stabilization of emulsions and suspensions, or for creating physical changes, such as viscosity changes, in products. Another well-known application is cell disruption of yeasts or bacteria in order to release intracellular products such as recombinant proteins. The development over the last few years of homogenizing equipment that operates at increasingly higher pressures has also stimulated research into the possible application of high-pressure homogenization as a unit process for microbial load reduction of liquid products. Several studies have indicated that gram-negative bacteria are more sensitive to high-pressure homogenization than gram-positive bacteria supporting the widely held belief that high-pressure homogenization kills vegetative bacteria mainly through mechanical disruption. However, controversy exists in the literature regarding the exact cause(s) of cell disruption by high-pressure homogenization. The causes that have been proposed include spatial pressure and velocity gradients, turbulence, cavitation, impact with solid surfaces, and extensional stress. The purpose of this review is to give an overview of the existing literature about microbial inactivation by high-pressure homogenization. Particular attention will be devoted to the different proposed microbial inactivation mechanisms. Further, the different parameters that influence the microbial inactivation by high-pressure homogenization will be scrutinized.

Capsular polysaccharides from serotypes 6B, 10A, 17F, 19A, 19F, and 20 contain a phosphodiester bond that connects the repeating units in these polysaccharides (also referred to as backbone phosphodiester bonds), and polysaccharides from serotypes 11A, 15B, 18C, and 23F contain a phosphodiester bond that links a side chain to their repeating units. Molecular weight measurements of the polysaccharides, using high performance size exclusion chromatography with tandem multiangle laser light scattering and refractive index detection, was used to evaluate the kinetics of hydrolysis. The measurement of molecular weight provides a high degree of sensitivity in the case of small extents of reaction, thus allowing reliable measurements of the kinetics over short times. Pseudo-first-order rate constants for these polysaccharides were estimated using a simple model that accounts for the polydispersity of the starting sample. It was found that the relative order of backbone phosphodiester bond instability due to base hydrolysis was 19A > 10A > 19F > 6B > 17F, 20. Degradation of side-chain phosphodiester bonds was not observed, although the high degree of sensitivity in measurements is lost in this case, due to the low contribution of the side chains to the total polysaccharide molecular weight. In comparison with literature data on pneumococcal polysaccharide 6A, 19A was found to be the more labile, and hence appears to be the most labile pneumococcal polysaccharide studied to date. The rate of hydrolysis increased at higher pH and in the presence of divalent cation, but the extent was lower than expected based on similar data on RNA. Finally, the differences in the phosphodiester bond stabilities were analyzed by considering stereochemical factors in these polysaccharides. These results also provide a framework for evaluation of molecular integrity of phosphodiester-bond-containing polysaccharides in different solution conditions.

Abstract
Modified high shear homogenization and ultrasound techniques were employed to produce solid lipid nanoparticles (SLNs). Model drug mifepristone had been incorporated in SLNs. The mean particle size measured by laser diffractometry (LD) was found to be 106 nm with a narrow particle distribution of polydispersity index, 0.278. Differential scanning calorimetry and X-ray diffraction measurements suggested that the majority of the SLNs were less ordered arrangement of crystals, and this was favorable for increasing the drug loading capacity. The drug entrapment efficiency (EE%) of SLNs was more than 87 percent and showed relatively long-term physical stability as the leakage was very small after being stored for one month. Therefore, seemed this modified method could prepare high quality SLNs loading lipophilic drugs. It is a simple, available and effective method to produce SLNs.

Abstract
A cell permeabilization method for the release of intracellular proteins from microbial cells was developed. The method was applied to the recovery of recombinant botulinum neurotoxin fragments, expressed intracellularly in the yeast Pichia pastoris, by suspending the cells in an aqueous solution containing N,N-dimethyltetradecylamine. For the botulinum neurotoxin serotype B C-terminal heavy chain fragment, 1.8 mg g(-1) biomass were recovered. For the botulinum neurotoxin serotype A C-terminal heavy chain fragment, 3.7 mg g(-1) biomass were recovered. The concentration of recombinant protein in the cell extracts remained stable for up to 48 and 24 h for the serotype B and serotype A fragments, respectively. The permeabilization method was compared with high-pressure homogenization; the permeabilization method proved to be both more selective and more efficient.
