Polymer Vesicles Containing Small Vesicles within Interior Aqueous Compartments and pH-Responsive Transmembrane Channels

摘要

Intermolecular packing of amphophilic block copolymers into vesicles is of particular interest, owing to the fundamental importance of such systems as a new class of polymer assemblies with well-controlled structures and potential biomedical applications. Similar to conventional liposomes, polymer vesicles usually form a continuous bilayer structure primarily consisting of the hydrophobic blocks of copolymers, but they exhibit markedly enhanced stability and feasibility of incorporating functional groups in response to external stimuli.
