Thin polymer films with the ability of both drug release and protein adsorption resistance were formed on silicon substrates and silica particles. The films were made of a block copolymer of poly(N-isopropylacrylamide) (p(AAm)) that can load and release drugs and poly(2-methoxyethyl methacrylate) (p(MEMA)) that can suppress protein adsorption. Aspirin and bovine serum albumin were respectively used as model substances for testing the abilities of the films to load and release drugs and to suppress protein adsorption. The films were immersed in a phosphate buffer saline (pH 7.4) for 100 days to evaluate their water resistance. The experimental results showed that the films have both drug release and protein adsorption resistance and are highly stable against PBS.
We prepared the silicon surface modified with a block copolymer of poly(N-isopropylacrylamide) (p(AAm)) and poly(2-methoxyethyl methacrylate) (p(MEMA)) and evaluated the ability of the surface to release drug and resist protein adsorption. Figure optionsDownload as PowerPoint slide
