Highly localized, selective deprotection chemistry and efficient grafting reactions in microcontacts between elastomeric stamps and reactive polystyrene‐ block ‐poly( tert ‐butyl acrylate) (PS 690 ‐ b ‐P t BA 1210 ) diblock copolymer films are developed. The procedure yields well‐defined protein–poly(ethylene glycol) (PEG) nanopatterns (see figure), which may find applications in, for example, cancer‐cell–surface interaction studies.
