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.
