Large‐area micropatterns of poly(acrylic acid) (PAA) nanodomains favorable for biological cell attachment are produced in a nonfouling poly(ethylene oxide) (PEO) matrix (see image). Nanoimprint‐assisted microcontact stripping techniques are used to micropattern polystyrene nanobeads deposited on PAA. Subsequent etching of the nanobeads, followed by deposition of PEO by plasma‐enhanced chemical vapor deposition, produces the fouling/non‐fouling surface.
