Abstract
Facile surface modification via the blending of lipids and block-co-polymers to assemble hybrid vesicles was investigated for improving cellular interaction and antigen delivery of poly(ethylene glycol) (PEG)-based polymersomes. Cationic lipids (DOTAP) incorporated into PEG-b-PBD polymersomes increased the binding and uptake of vesicles by antigen-presenting cells, while preserving the stability and biocompatibility of PEG-based polymersomes, resulting in the enhanced cellular delivery of a loaded lipid antigen sulfatide.
