摘要：
Aqueous initiators for continuous activator regeneration atom transfer radical polymerization (ICAR ATRP) was applied to graft well defined acrylamide, N, N-dimethylacrylamide and N-vinylimidazole homo and block copolymers from a model protein initiator (bovine serum albumin (BSA)) under bio-relevant conditions. Using N-vinylimidazole as a ligand catalytic biohybrid nanoparticles were prepared by loading palladium into a block copolymer of poly(N-vinylimidazole)-b-poly(oligo(ethylene oxide) acrylate) grafted from BSA. The protein-polymer biohybrid catalyst successfully catalyzes Suzuki-Miyaura couplings in aqueous media under aerobic conditions.
