Covalent immobilization of antibody fragments on well-defined polymer brushes via site-directed method.
TL;DR: Antigen/antibody binding on the polymer brushes was more preferable than that on epoxysilane films as a control surface and the activity of the antibodies immobilized on the block copolymer brushes having biocompatible PMPC was greater than thaton other surfaces that did not have PMPC in their structures.

Surface modification with well-defined biocompatible triblock copolymers: Improvement of biointerfacial phenomena on a poly(dimethylsiloxane) surface
TL;DR: To improve interfacial phenomena of poly(dimethylsiloxane) (PDMS) as biomaterials, well-defined triblock copolymers were prepared as coating materials by reversible addition-fragmentation chain transfer (RAFT) controlled polymerization, effective in improving the surface properties of PDMS.

Site-Specific Dense Immobilization of Antibody Fragments on Polymer Brushes Supported by Silicone Nanofilaments
TL;DR: For site-specific dense immobilization of antibodies on a solid support, phosphorylcholine copolymer brushes on silicone nanofilaments were prepared by a "grafting from" process and pyridyl disulfide groups were introduced into the polymer chains.

TL;DR: The fact that Pt-BMA brushes grown from nanopores were almost featureless implies that self-aggregation of PMPC brushes is truly a consequence of phase incompatibility between hydrophilic PMPC brushed and hydrophobic tris(TMS).

TL;DR: To better understand protein/material and cell/material interactions at the submolecular level, well-defined polymer brushes consisting of poly(2-methacryloyloy loxyethyl phosphorylcholine) (PMPC) on silicon wafers were prepared by atom transfer radical polymerization (ATRP).
