This study examines in vitro and in vivo biodegradation and biocompatibility of a thermogelling polymeric material, which we call a mixture hydrogel. The mixture contains two ABA-type triblock copolymers poly(d,l-lactic acid-co-glycolic acid)-b-poly(ethylene glycol)-b-poly(d,l-lactic acid-co-glycolic acid) (PLGA-PEG-PLGA) with different block ratios, and one polymer is soluble in water, but the...
Targeted drug delivery to endothelial cells lining the vasculature can improve treatment of many pathologies. Intercellular adhesion molecule-1 (ICAM-1), a transmembrane glycoprotein overexpressed in many diseases, is a good determinant for endothelial targeting of drug nanoparticles (NPs). In this study we synthesized surfactant-free, FITC-labeled poly(lactic-co-glycolic) acid (PLGA) NPs coate...
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 (lactic-co-glycolic) acid microspheres are amenable to a number of biomedical procedures that support delivery of cells, drugs, peptides or genes. Hydrophilisation or wetting of poly (lactic-co-glycolic) acid are an important pre-requisites for attachment of cells and can be achieved via exposure to plasma oxygen or nitrogen, surface hydrolysis with NaOH or chloric acid, immersion in ethan...
The effect of modifying the well-established pharmaceutical polymer PLGA by different PEG-containing block-copolymers on the preparation of ovalbumin (OVA) loaded PLGA nanoparticles (NPs) was studied. The used polymers contained poly(d,l-lactic-co-glycolic acid) (PLGA), polyethylene glycol (PEG) and poly(allyl glycidyl ether) (PAGE) as building blocks. The double emulsion technique yielded sphe...
background: disulfiram is oral aldehyde dehydrogenase (aldh) inhibitor that has been used in the treatment of alcoholism. recent studies show that this drug has anticancer properties; however, its rapid degradation has limited its clinical application. encapsulation of disulfiram polymeric nanoparticles (nps) may improve its anticancer activities and protect rapid degradation of the drug. mater...

INTRODUCTION Extensively used polymers in biomedical applications are naturally occurring or synthetic compounds consisting of large molecules obtained from linking of simple monomers. Potential biomedical applications of these polymers include carrier based drug delivery systems, tissue engineering scaffold and cell culture supports [1]. Polymer based drug delivery system can control the rate ...
Poly(lactic-co-glycolic acid) (PLGA) is the most widely used biomaterial for microencapsulation and prolonged delivery of therapeutic drugs, proteins and antigens. PLGA has excellent biodegradability and biocompatibility and is generally recognized as safe by international regulatory agencies including the United States Food and Drug Administration and the European Medicines Agency. The physico...
