Micropatterning of hydrophilic polyacrylamide brushes to resist cell adhesion but promote protein retention.

Contrary to a prevailing concept on protein adsorption and cell adhesion, novel micropatterned polyacrylamide (PAAm) brushes that can resist cell adhesion but promote protein retention are created through patterning of ATRP initiators and surface-initiated ATRP on a polymer substrate.
