摘要:
Core-shell polymer blend particles are described. The particles include a pH-responsive polymeric shell and a pH-irresponsive polymeric core. The core can include a biodegradable hydrolysable polymer and the shell can include a pH-responsive copolymer that can include constitutional units that are cationic and/or anionic at physiological pH. The core-shell polymer blend particles can allow the controlled delivery of agents into a plurality of distinct intracellular compartments.
