Scheme 1From: Improved gene delivery to K-562 leukemia cells by lipoic acid modified block copolymer micellesSynthetic routes. a Synthesis of the LAMA monomer via DCC/DMAP esterification coupling reaction. b A chain transfer agent, CPAETC, was used to synthesize a macro-CTA, PDMAEMA, via RAFT polymerization. The macro-CTA was then used to synthesize the block copolymer under same conditionsBack to article page
