Abstract
A class of cationic supramolecular block copolymers with readily controlled charges has been exploited. Upon post-synthetic structural optimization, this copolymer exhibits comparable biocompatibility, greatly improved pDNA condensation capability and biostability, and further enhanced transfection efficiency in vitro. This work provides valuable insight into the creation of advanced nonviral vectors for gene delivery.
