Webb10 sep. 2012 · These shortcomings can possibly be overcome by using relatively hydrophilic PEG–PLGA based block copolymers for fabrication of particulate systems to encapsulate excessively hydrophilic drugs. Further, in pulmonary drug delivery, large porous particles have been reported to provide longer residence. WebbWhile PLGA is naturally hydrophobic, PEG is the opposite, so the combination of both is amphiphilic, facilitating the emulsification process. PEG-PLGA nanoparticles can be prepared by two methods: using of PLGA-PEG block copolymers or by adding a PEG coating after the preparation of the PLGA nanoparticles.
