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...

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...

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...

Chitosan (CS)-modified poly(d,l-lactic-co-glycolic) acid (PLGA) nanoparticles (NPs) were prepared and their lung targetability after intravenous administration was elucidated. PLGA NPs (mean diameter: 225nm; polydispersity index: 0.11; zeta potential: -15mV), 0.2% (w/v) CS-coated PLGA NPs (CS02-PLGA NPs, mean diameter: 264nm; polydispersity index: 0.17; zeta potential: -7mV), and 0.5% (w/v) CS-...

Effective chemotherapy remains an important issue in the treatment of drug resistant cancer. The aim of the present study was to establish novel polymeric nanoparticles composed of the antitumor drug, doxorubicin (DOX), and an inhibitor of the drug efflux pump-associated protein, P-glycoprotein (P-gp), in order to overcome drug resistance in tumor cells. Poly(D,L-lactide-co-glycolide) (PLGA), D...

This study concentrates on the development of biodegradable nanofiber membranes with controlled drug release to ensure reduced tissue adhesion and accelerated healing. Nanofibers of poly(lactic-co-glycolic acid) (PLGA) loaded with epigallocatechin-3-O-gallate (EGCG), the most bioactive polyphenolic compound in green tea, were electrospun. The physicochemical and biomechanical properties of EGCG...

Poly((D,L)lactic-glycolic)acid-star glucose (PLGA-Glc) polymer-based nanoparticles (NPs) were fabricated for tumor-targeted delivery of docetaxel (DCT). NPs with an approximate mean diameter of 241 nm, narrow size distribution, negative zeta potential, and spherical shape were prepared. A sustained drug release pattern from the developed NPs was observed for 13 days. Moreover, drug release from...

This work reports the feasibility of caffeic acid grafted PLGA (g-CA-PLGA) to design biodegradable sterile microspheres for the delivery of proteins. Ovalbumin (OVA) was selected as model compound because of its sensitiveness of γ-radiation. The adopted grafting procedure allowed us to obtain a material with good free radical scavenging properties, without a significant modification of Mw and T...
