Article Description

Nitrate-containing amphiphilic block copolymer chains were self-assembled into micellar nanostructures as a reservoir for the slow-release delivery of nitric oxide (NO). Poly(oligo(ethylene glycol) methyl ether methacrylate)-block- poly(vinyl benzyl chloride-co-styrene) was prepared by reversible addition fragmentation chain transfer (RAFT) polymerization. Pendant chloro- groups in the polymer backbone were reacted with silver nitrate (AgNO) to introduce nitrate functionality. The nitrate-containing micelles proved to be stable in water, with no detectableNOrelease. The release ofNOwas then triggered by exposure to glutathione, and it was found that 36 and 99% of NO was released at 37 and 60° C, respectively, after 21 h. © 2014 Wiley Periodicals, Inc.
