چکیده
N-[2-(acryloyloxy)ethyl]-N,N-dimethyl-N-butylammonium iodide was successfully photo-polymerized from native and thiolated PDMS surface, in the presence of benzophenone. The directly indirectly grafted surfaces exhibited quaternary ammonium densities about 1015 1017 N+.cm?2, respectively, very high hydrophilicity compared to non-grafted surfaces. live dead tests performed by fluorescence microscopy revealed an effective contact bactericidal effect this surface against Escherichia coli Staphylococcus epidermidis.

Patterned poly(N-isopropylacrylamide) (PNIPAAm) brushes were fabricated on oxidized silicon wafers by surface-initiated atom transfer radical polymerization of N-isopropylacrylamide from a micropatterned initiator. The patterned surface initiator was prepared by microcontact-printing octadecyltrichlorosilane and backfilling with 3-(aminopropyl)triethoxysilane followed by amidization with 2-brom...
