A self-assembly approach to chemical micropatterning of poly(dimethylsiloxane)

• The surface of a silicone elastomer (poly(dimethylsiloxane); PDMS) can be selectively modified through minimization of interfacial free energy and self-assembly of functional molecules at the surface by mirroring the distribution of template surface energies (see scheme for formation of POEGMA brushes; SAM=self-assembled monolayer, bipy=2,2′-bipyridyl, POEGMA=poly[oligo(ethylene glycol) methacrylate]).
