Microcapsule membranes are fabricated with PLGA through double emulsion method and solvent evaporation method. In outer aqueous phase, surfactants such as PVA were replaced with metal salts as CaCl2 and MgCl2. Inside the microcapsule membrane, BSA was encapsulated as the model drug. Morphologies, BAS encapsulation efficiencies and BAS releasing behaviors are investigated. Through the process, microcapsule membranes with diameters of μm are generated and, through this work, we got a conclusion that the metal salts could be a good choice to replace PVA to solidify the microcapsule membrane surfaces.
