Neutron Reflectivity Study of Protein Adsorption onto Cell Membrane-inspired Anti-Fouling Phospholipid Polymer Brush Surface

, , &
We grafted 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer brush from the silicon wafer surface through Cu (0) mediated controlled radical polymerization (CuCRP) to mimic cell membrance. Excellent control over graft density and film thickness was acheived by reaction condition variation. An optimal thickness of PMPC for protein resistance was estabilished. The adsorption then was found to increase together with the PMPC thickness. This can be either attributed to an increased surface adsorption or to protein penetration within...
