Figure 1. Chemical structures of polymer brushes used for biomedical applications.
A) General strategy for polymer brush growth from a surface. An ATRP initiator is attached to a substrate from which a polymer brush is grown by surface-initiated ATRP. B) Architecture of surface tethered polymer brush (left panel) and commonly used polymer backbones and side-chains used for polymer brush growth, including polymethacrylates and polyacrylates (middle panel). A set of neutral and zwitterionic monomers are also shown (right panel).
