Abstract
AbstractIn this study, it was aimed to introduce a transdermal drug delivery system with dissolving microneedles (DMNs) based on gelatin (GEL) and sodium carboxymethyl cellulose (NaCMC) for lidocaine hydrochloride (LidoHCl) delivery. Different ratios of GEL and NaCMC were mixed, loaded with an active agent of LidoHCl, and treated with glutaraldehyde (GTA) as a crosslinker agent. Prepared hydrogels were cast into a silicon mold. Hereby, microneedles (MNs) with 500 µm height, 35° needle angle, 40-µm tip radius, and 960-µm tip-to-tip distance were fabricated. Samples containing LidoHCl 40%, GEL/NaCMC 5:1 (wt/wt), and polymer/GTA ratio 3.1 (wt/wt) showed the highest drug release ability (t < 10 min) with proper mechanical properties in comparison with other samples. Due to the drug release in a short time (fewer than 10 min), this drug delivery system can be used for rapid local anesthesia for pain relief as well as before minor skin surgeries.

Biopolymer Hydrogel Scaffolds Containing Doxorubicin as A Localized Drug Delivery System for Inhibiting Lung Cancer Cell Proliferation. Polymers (Basel) 2021; 13:polym13203580. [PMID: 34685337 PMCID: PMC8540863 DOI: 10.3390/polym13203580] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2021] [Revised: 10/13/2021] [Accepted: 10/15/2021] [Indexed: 12/02/2022] Open
Abstract
A hydrogel scaffold is a localized drug delivery system that can maintain the therapeutic level of drug concentration at the tumor site. In this study, the biopolymer hydrogel scaffold encapsulating doxorubicin was fabricated from gelatin, sodium carboxymethyl cellulose, and gelatin/sodium carboxymethyl cellulose mixture using a lyophilization technique. The effects of a crosslinker on scaffold morphology and pore size were determined using scanning electron microscopy. The encapsulation efficiency and the release profile of doxorubicin from the hydrogel scaffolds were determined using UV-Vis spectrophotometry. The anti-proliferative effect of the scaffolds against the lung cancer cell line was investigated using an MTT assay. The results showed that scaffolds made from different types of natural polymer had different pore configurations and pore sizes. All scaffolds had high encapsulation efficiency and drug-controlled release profiles. The viability and proliferation of A549 cells, treated with gelatin, gelatin/SCMC, and SCMC scaffolds containing doxorubicin significantly decreased compared with control. These hydrogel scaffolds might provide a promising approach for developing a superior localized drug delivery system to kill lung cancer cells.

Abstract
Tuberculosis (TB) is a contagious airborne disease caused by Mycobacterium tuberculosis, which primarily affects human lungs. The progression of drug-susceptible TB to drug-resistant strains, MDR-TB and XDR-TB, has become worldwide challenge in eliminating TB. The limitations of conventional TB treatment including frequent dosing and prolonged treatment, which results in patient’s noncompliance to the treatment because of treatment-related adverse effects. The non-invasive pulmonary drug administration provides the advantages of targeted-site delivery and avoids first-pass metabolism, which reduced the dose requirement and systemic adverse effects of the therapeutics. With the modification of the drugs with advanced carriers, the formulations may possess sustained released property, which helps in reducing the dosing frequency and enhanced patients’ compliances. The dry powder inhaler formulation is easy to handle and storage as it is relatively stable compared to liquids and suspension. This review mainly highlights the aerosolization properties of dry powder inhalable formulations with different anti-TB agents to understand and estimate the deposition manner of the drug in the lungs. Moreover, the safety profile of the novel dry powder inhaler formulations has been discussed. The results of the studies demonstrated that dry powder inhaler formulation has the potential in enhancing treatment efficacy.

Abstract
Three-dimensional porous nanocomposites consisting of gelatin-carboxymethylcellulose (CMC) cross-linked by carboxylic acids biopolymers and monophasic hydroxyapatite (HA) nanostructures were fabricated by lyophilization, for soft-bone-tissue engineering. The bioactive ceramic nanostructures were prepared by a novel wet-chemical and low-temperature procedure from marine wastes containing calcium carbonates. The effect of surface-active molecules, including sodium dodecyl sulfate (SDS) and hexadecyltrimethylammonium bromide (CTAB), on the morphology of HA nanostructures is shown. It is demonstrated that highly bioactive and monophasic HA nanorods with an aspect ratio > 10 can be synthesized in the presence of SDS. In vitro studies on the bioactive biopolymer composite scaffolds with varying pore sizes, from 100 to 300 μm, determine the capacity of the developed procedure to convert marine wastes to profitable composites for tissue engineering.

Abstract
The comparison between Tramadol drug loaded microspheres prepared from gelatin/sodium carboxymethyl cellulose (NaCMC) and those prepared from gelatin/sodium carboxymethyl nanocellulose (NaCMNC) in presence of glutaraldehyde (GA) as cross linker was carried out. Cellulose isolated from rice straw was hydrolyzed using 65% H2SO4 to prepare nanoparticles with average particle size ranging from 44 to 66 nm. Various formulations of gelatin/NaCMC and gelatin/NACMNC were prepared with different ratios of amounts of gelatin, NaCMC/NaCMNC, and GA. Microspheres were characterized by fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy. The FTIR spectroscopy results confirmed the structure of microsphere and the absence of chemical interactions among Tramadol drug, polymer, and crosslinking agent. The ultraviolet spectroscopy showed 68% efficiency of the drug encapsulation using cellulose, while 55% for nanocellulose. The equilibrium water uptake decreased from 646 to 329% for cellulose microspheres, when the amount of GA increased from 5 to 10 mL. In contrast, the equilibrium water uptake decreased significantly from 501 to 33.7% for nanocellulose microspheres. The yield percentage enhanced from 54.67 to 80% for nanocellulose microspheres. The in vitro release rate was also calculated. The percent cumulative release of drug was significantly increased at the first 2 h and then a slow increase was further noticed. In general, the nanocellulose microsphere showed lower release rates than cellulose. None of the prepared microsphere presented 100% drug release until 12 h.

Abstract
Anti-tuberculosis drug delivery has remained a challenge due to inconsistent bioavailability and inadequate sustained-release properties leading to treatment failure. To resolve these drawbacks, a lipopolysaccharide polyelectrolyte complex (PEC) encapsulated with rifampicin (RIF) (as the model drug) was fabricated, using the solvent injection technique (SIT), with soy lecithin (SLCT), and low-molecular-weight chitosan (LWCT). The average particle size and surface charge of RIF-loaded PEC particulates was 151.6 nm and + 33.0 nm, respectively, with noted decreased particle size and surface charge following increase in SLCT-LWCT mass ratio. Encapsulation efficiency (%EE) and drug-loading capacity (%LC) was 64.25% and 5.84%, respectively. Increase in SLCT-LWCT mass ratio significantly increased %EE with a marginal reduction in %LC. In vitro release studies showed a sustained-release profile for the PEC particulate tablet over 24 h (11.4% cumulative release) where the dominant release mechanism involved non-Fickian anomalous transport shifting towards super case II release as SLCT ratios increased (6.4% cumulative release). PEC-tablets prepared without SIT presented with rapid Fickian-diffusion-based drug release with up to 90% RIF release within 4 h. Ex vivo permeability studies revealed that lipopolysaccharide PEComplexation significantly increased the permeability of RIF by ~ 2-fold within the 8-h study period. These results suggest successful encapsulation of RIF within a PEC structure while imparting increased amorphic regions, as indicated by x-ray diffraction, for potential benefits in improved drug dissolution, bioavailability, and dosing.

Abstract
Phosphate-buffered saline (PBS) adsorption on model films composed of gelatin and nanofibrillated celluloses (NFCs) with different aldehyde and carboxyl contents was studied by means of the quartz crystal microbalance with dissipation (QCM-D) technique in this study. The results showed that frequency shift (Δ f) due to PBS adsorption increased with increasing gelatin content to 50% in NFC-containing films. The dissipation shift and adsorption rate of PBS followed the same trend. Model films with NFC-1 having 1.22 mmol/g aldehyde and 0.6 mmol/g carboxyl groups adsorbed more PBS than those consisting of NFC-2 with 0.25 mmol/g aldehyde and 1.15 mmol/g carboxyl groups except for film composed of 50% gelatin. However, adsorption rate of PBS was found to be slower for NFC-1 containing film because the acetal and amidol bonds formed by functional groups in the network of cellulose and gelatin needed more time to let PBS migrate into the films.

Abstract
New biocompatible materials have enabled the direct 3D printing of complex functional living tissues, such as skeletal and cardiac muscle. Gelatinmethacryloyl (GelMA) is a photopolymerizable hydrogel composed of natural gelatin functionalized with methacrylic anhydride. However, it is difficult to obtain a single hydrogel that meets all the desirable properties for tissue engineering. In particular, GelMA hydrogels lack versatility in their mechanical properties and lasting 3D structures. In this work, a library of composite biomaterials to obtain versatile, lasting, and mechanically tunable scaffolds are presented. Two polysaccharides, alginate and carboxymethyl cellulose chemically functionalized with methacrylic anhydride, and a synthetic material, such as poly(ethylene glycol) diacrylate are combined with GelMA to obtain photopolymerizable hydrogel blends. Physical properties of the obtained composite hydrogels are screened and optimized for the growth and development of skeletal muscle fibers from C2C12 murine cells, and compared with pristine GelMA. All these composites show high resistance to degradation maintaining the 3D structure with high fidelity over several weeks. Altogether, in this study a library of biocompatible novel and totally versatile composite biomaterials are developed and characterized, with tunable mechanical properties that give structure and support myotube formation and alignment.

Abstract
The present study aims at synthesizing gelatin A-pectin complex coacervates and encapsulation of theophylline in the polymer system. Variation and optimization of different reaction parameters such as pH, ratio between the polymers and cross-linker concentration was carried out to attain higher product yield. Relative viscosity, turbidity and UV-visible measurements were done for optimization. The optimum ratio between gelatin A-pectin was fixed at weight ratio 42:8 and pH=3.5. It was further observed that adhesion between the microcapsules decreased by the use of sodium carboxymethyl cellulose (SCMC) to the coacervate. The synthesized microcapsules were characterized by using spectroscopic techniques to assess their formation, drug loading and chemical interaction between theophylline and coacervate. Scanning electron microscopy (SEM) revealed the formation of microcapsules. Study relating to the encapsulation efficiency and swelling of the complex coacervates were also carried out.

Abstract
Background Bovine serum albumin nanoparticles loaded with isoniazid and rifampicin (INH-RFP-BSA-NPs) were prepared and their release characteristics were studied in vitro. Material/Methods The INH-RFP-BSA-NPs were prepared by a modified self-emulsion solvent diffusion method, with albumin and polylactic acid used as carriers and to form the nanoparticles structure. Transmission electron microscopy was used to observe the morphology of the INH-RFP-BSA-NPs. The size distribution of the INH-RFP-BSA-NPs were assessed using a submicron particle-size analyzer for drug loadings, and the coating rate of the INH-RFP-BSA-NPs was measured by high-performance liquid chromatography. A dynamic membrane dialysis method was used to study the in vitro release characteristics of the INH-RFP-BSA-NPs. Results The INH-RFP-BSA-NPs were smooth, sphere-like, relatively uniform in size, and well-dispersed, and the average diameter was 60.5±4.6 nm. Drug loading and entrapment efficiencies were high, at 19.8% and 87.8% for isoniazid, respectively, and 20.1% and 98.0% for rifampicin, respectively. Drug release was slow and sustained with 97.02% INH cumulative release at 6 days, and full release of RFP requiring 5 days. Conclusions INH-RFP-BSA-NPs exhibit uniform NP diameter, good dispersion, high drug loading and encapsulation rates, and have sustained release properties.

Abstract
Polysaccharide-protein complex coacervates are amongst the leading pair of biopolymer systems that has been used over the past decades for encapsulation of numerous active ingredients. Complex coacervation of polysaccharides and proteins has received increasing research interest for the practical application in encapsulation industry since the pioneering work of complex coacervation by Bungenburg de Jong and co-workers on the system of gelatin-acacia, a protein-polysaccharide system. Because of the versatility and numerous potential applications of these systems essentially in the fields of food, pharmaceutical, cosmetics and agriculture, there has been intense interest in recent years for both fundamental and applied studies. Precisely, the designing of the micronscale and nanoscale capsules for encapsulation and control over their properties for practical applications garners renewed interest. This review discusses on the overview of polysaccharide-protein complex coacervates and their use for the encapsulation of diverse active ingredients, designing and controlling of the capsules for delivery systems and developments in the area.

Abstract
Astaxanthin oleoresin (AO) has a number of beneficial physiological functions. However, its sensitivity to light, heat, oxygen and gastric fluids has limited its application. In this paper, we describe the preparation of AO enteric microcapsules by coacervation to improve its stability and enteric solubility, and evaluate their efficacy by measuring the drug loading, encapsulation efficiency, optical microscopic appearance, stability, in vitro release and bioavailability. The results obtained showed that the AO enteric microcapsules possessed a high encapsulation efficiency (85.9%), a satisfactory in vitro release profile, and the ability of the microencapsulated AO to resist the effects of light, heat and oxygen was improved by 2.2-fold, 3.1-fold and 2.4-fold, respectively, during storage. In addition, the bioavailability of AO microcapsules was approximately 1.29-fold higher than AO, which is important for pharmaceutical applications and as a functional food.

Abstract
Collagen–carboxymethyl cellulose–tricalcium phosphate cryogels were prepared for diverse biomedical applications. Further chemical and structural characterizations were performed by Fourier transform infrared spectra, thermogravimetric analysis, X-ray crystallography, and scanning electron microscopy. The mechanical properties were tested by unconfined compression test. Moreover, hemocompatibility of the cryogels was also evaluated by basic biochemical blood testing. Chemical and structural analysis results demonstrate the achievement of the cross-linking without any major alteration in collagen and carboxymethyl cellulose with a thermally and structurally stable blend formation. Scanning electron micrographs demonstrate the multi-lamellar formation with macro- and micro-pore compositions which can correlate with water uptake results of the cryogels. Hemocompatibility evaluations exhibited that the cryogels are non-toxic and blood-compatible. The overall results including mechanical testing of these tricalcium phosphate–consisting collagen/carboxymethyl cellulose cryogels may have potential use as a material for hard tissue regeneration.

Abstract
The coacervation between gelatin and sodium alginate for ginger volatile oil (GVO) microencapsulation as functions of mass ratio, pH and concentration of wall material and core material load was evaluated. The microencapsulation was characterized by scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), and thermal gravimetric analysis (TGA). SEM and FT-IR studies indicated the formation of polyelectrolyte complexation between gelatin and sodium alginate and successful encapsulation of GVO into the microcapsules. Thermal property study showed that the crosslinked microparticles exhibited higher thermal stability than the neat GVO, gelatin, and sodium alginate. The stability of microencapsulation of GVO in a simulated gastric and an intestinal situation in vitro was also studied. The stability results indicated that the release of GVO from microcapsules was much higher in simulated intestinal fluid, compared with that in simulated-gastric fluid.

Abstract
The objective of this study was to compare a novel controlled release tablet formulation based on interpolyelectrolyte complex (PEC). Interpolymer interactions between the countercharged polymers like Eudragit® EPO (polycation) and hypromellose acetate succinate (polyanion) and Eudragit® EPO and hypromellose phthalate (polyanion) were investigated with a view to their use in per oral controlled release drug delivery systems. The formation of inter-macromolecular ionic bonds between cationic polymer and anionic polymer was investigated using Fourier transform infrared (FT-IR) spectroscopy and differential scanning calorimetry. The FT-IR spectra of the tested polymeric matrices are characterized by visible changes in the observed IR region indicating the interaction between chains of two oppositely charged copolymers. The performance of the in situ formed PEC as a matrix for controlled release of drugs was evaluated, using acetaminophen as a model drug. The dissolution data of these matrices were fitted to different dissolution models. It was found that drug release followed zero-order kinetics and was controlled by the superposition of the diffusion and erosion. These profiles could be controlled by conveniently modifying the proportion of the polymer ratio, polymer type, and polymer concentration the in the tablets.

Abstract
Homogeneous and bulk carboxymethyl cellulose hydrogel and aerogel were prepared by a novel process, using Fe(3+) and d-(+)-gluconic acid-lactone as cross-linker and releasing agent, respectively. The results showed that the mass fraction of Fe(3+) has a great effect on CMC aerogels' structure, crystallization and morphology. By adjusting the mass fraction of Fe(3+), granular, three-dimensional network and rod-like morphology were obtained, responding to varying density and porosity. The aerogel had low density (low to 0.0568 g/cm(3)) and high porosity (up to 90.45%). Meantime. Combination patterns between carboxylate ion and iron ion were checked by FTIR. Furthermore, with the addition of Fe(3+), lattice mismatch of CMC emerged and led to decreasing crystalline degree and thermal stability. This work would play an important role in the handy and extensive application of CMC aerogels.

Abstract
CONTEXT The coating material of magnetic nanoparticles plays a great role in drug delivery application. The coatings not only increase the stability of the nanoparticles but also improve the drug release pattern, biocompatibility and mucoadhesivity. OBJECTIVE Montmorillonite (MMT) containing magnetic iron oxide nanoparticles coated with polyelectrolyte complex (PEC) of carboxymethyl starch-chitosan were prepared for controlled release applications. METHOD The PEC-coated nanoparticles were characterised by Fourier Transmission Infra-red spectroscopy and X-ray diffraction, scanning electron microscope, transmission electron microscope, and dynamic light scattering. Cytotoxicity study was performed by MTT assay analysis. Mucoadhesivity test was performed by using in vitro wash off and ex vivo method. RESULT The coating of PEC showed good stability, biocompatibility and mucoadhesivity of the iron oxide magnetic nanoparticles. MMT addition enhanced the swelling, drug loading and release and also the cytotoxicity and mucoadhesivity of the nanoparticles. CONCLUSION This study revealed that the MMT incorporated PEC of CMS-CS can be effectively used for coating of iron oxide nanoparticles.
