Facile synthesis of a silicon surface modified by poly(N-isopropylacrylamide-co-N-acryloyl glucosamine) [poly(NIPAAm-co-AGA)] brushes prepared by surface-initiated single electron transfer-living radical polymerization (SET-LRP) in water is described. The copolymerization exhibits a fast polymerization rate and good controllability. Moreover, copolymers with variable AGA content and comparable thickness are synthesized and the effect of the AGA content on the wettability and thermoresponsive property of the surface are studied. Also, both the non-specific protein resistance ability and the specific protein adsorption ability of the Si-poly(NIPAAm-co-AGA) surface are investigated and the results indicate that the copolymer-grafted surface demonstrates enhanced resistance to non-specific protein adsorption and shows selective recognition of Concanavalin A (Con A). Together, these results prove that aqueous SET-LRP is promising for facile surface modification.
