    Abstract:
    For site-specific dense immobilization of antibodies on a solid support, we prepared phosphorylcholine copolymer brushes on silicone nanofilaments. The nanofilaments were prepared on a silicon wafer by treatment with trichloromethylsilane (MeSiCl 3). To generate Si-OH groups on the nanofilaments, O 2 plasma was irradiated on the surface. Initiators for atom transfer radical polymerization (ATRP) were then coupled on the filaments. Phosphorylcholine copolymer brushes were prepared by a "grafting from" process, and pyridyl disulfide groups were introduced into the polymer chains. F(ab') fragments were then specifically immobilized onto these surfaces via a thiol-disulfide interchange reaction. The amount of antibodies immobilized on the nanofilament-supported copolymer brushes was approximately 65 times greater than that on smooth wafer-supported copolymer brushes.
