Preparation, characterization and reduction of burst release of bovine serum albumin (BSA) from biodegradable PLGA microspheres
In this study, model protein bovine serum albumin (BSA) loaded poly(lactide-co-glycolide) (PLGA) microspheres have been prepared by a conventional water-in-oil-in-water (w/o/w) and a modified water-in-oil-in-oil-in-water (w/o/o/w) double emulsion solvent evaporation method. The prepared microspheres...
