Abstract [en]

Controlling cell behavior oil biomaterial surface is the ultimate goal of cell and tissue engineering. Fabrication of biomaterials with alternatively hydrophilic/hydrophobic surface of parallel nanopatterned groves can provide biomaterial surfaces for the study of cell-surface interactions. In the present communication, masked vapor-phase photografting was used in patterning functional groups on flat polymeric substrates using poly (dimethylsiloxane) (PDMS) channels. Surface patterns were fabricated by W-initiated photografting in the presence of a patterned PDMS mask. The approach is exemplified by patterning maleic anhydride (MAH) and acrylamide (AAm) onto poly (methyl methacrylate) (PMMA). The method offers another means to chemically functionalize and pattern polymer surface at the same time.
