Abstract

Entrapment of proteins in biodegradable nanospheres has been widely investigated as a technique to produce sustained release formulations for protein or anti-cancer drugs administration. Amphiphilic PLLA-mPEG diblock copolymer was prepared by ring opening polymerization (ROP) to form polymeric nanoparticles with a core-shell structure. The main encapsulation technique done is a water-in-oil-in-water (w/o/w) solvent evaporation technique. Here, protein was encapsulated using a newly developed water-in-oil emulsion-solvent diffusion technique. This technique leads to the formation of an emulsion combined with the immediate precipitation of the PLLA-mPEG. This phenomenon is caused by the diffusion of the polymer solvent to an external organic phase.
