Age-related macular degeneration (AMD) is the leading cause of certified vision loss worldwide. The standard treatment for neovascular AMD involves repeated intravitreal injections of therapeutic proteins directed against vascular endothelial growth factor, such as ranibizumab. Biodegradable polymers, such as poly(lactic-co-glycolic acid) (PLGA), form delivery vehicles which can be used to trea...
In this study, fluconazole (FLZ) loaded poly (lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) were prepared with two different formulations consisting of polyvinyl alcohol (PVA) and PVA-rhamnolipid (R) in order to improve antibiofilm activity against Candida albicans ATCC 90028. The encapsulation efficiency, drug loading capacity, in-vitro release, characterization these compared. Character...
The Layer by Layer (LBL) technique, based on the alternative assembly of oppositely charged polyelectrolyte molecules, is a very versatile tool for the fabrication of thin polymer film with controlled features at the nanoscale [2]. We have applied the LBL technique to encapsulate purified total RNA between polyelectrolyte layers as a negative charged biopolyelectrolyte in Chitosane/Alginate/RNA...
Poly(lactic-co-glycolic acid) (PLGA) is a biocompatible, biodegradable polymer approved by the FDA and EMA, which most widely used in field of health. In this study, PLGA was synthesized primarily from lactide glycolide polycondensation ring-opening polymerization. Then, amino acid derivatives were reaction acids presence 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC). The polymers PLGA, P...
Poly(D,L-lactic-co-glycolic acid) (PLGA) microspheres were prepared by an oil/water emulsion solvent evaporation method to use as an injectable microcarrier for cell delivery. Three different kinds of PLGA microspheres having hydrophobic, negatively charged, and positively charged surfaces were prepared. Hydrophobic and negatively charged PLGA microspheres were prepared by using terminally capp...
AbstractThe aim of the present study was to formulate poly (lactide-co-glycolide) (PLGA) nanoparticles loaded with 18-β-glycyrrhetinic acid (GLA) with appropriate physicochemical properties and antimicrobial activity. GLA loaded PLGA nanoparticles were prepared with different drug to polymer ratios, acetone contents and sonication times and the antibacterial activity of the developed nanopartic...
Lysozyme, as a model protein, was precipitated through the formation of protein-Zn complex to micronize for subsequent encapsulation within poly (lactic-co-glycolic acid) (PLGA) microspheres. Various parameters, including pH, type and concentration of added salts and protein concentration, were modified to optimize the yield of protein complexation and precipitation. The resulting protein parti...
Polymeric particles and liposomes are efficient tools to overcome the low immunogenicity of subunit vaccines. The aim of the present study was formulation and optimization of a new cationic lipid-modified PLGA nanoparticles (NPs) as a delivery system for Mycobacterium tuberculosis HspX/EsxS fusion protein. The cationic lipid-modified PLGA NPs containing HspX/EsxS fusion protein were prepared us...
Inhalable glycol chitosan-coated poly(lactic-co-glycolic acid) (PLGA) nanoparticles containing palmitic acid-modified exendin-4 (Pal-Ex4) (chitosan Pal-Ex4 PLGA NPs) were prepared and characterized. The surface morphology, particle size, and zeta potential of chitosan Pal-Ex4 PLGA NPs were investigated, and the adsorption and cytotoxicity of chitosan Pal-Ex4 PLGA NPs were evaluated in human lun...
