Graphical Abstract
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.
