Novel aspects of encapsulation and delivery using polymersomes

Polymersomes are nanoscopic (e.g. nanometer-sized) vesicles formed by amphiphilic block copolymers. They represent the more robust and versatile macromolecular counterparts to the well-established lipid vesicles or liposomes. Recently, considerable efforts have been made to produce them in a uniform and functional manner. New techniques such as artificial endocytosis and electroporation have also been developed to achieve payload encapsulation. In this mini review, we discuss these and other recent developments in making polymersomes an actual alternative for biomedical applications.
