A New Method toward Microengineered Surfaces Based on Reactive Coating

By using chemical vapor deposition (CVD) a range of substrates can be coated with a highly reactive polymer containing pentafluorophenol ester groups. A biotin-modified pattern is generated on the substrate by microcontact printing; such a pattern interacts specifically with fluorescein-conjugated streptavidin and thereby the pattern becomes observable with fluorescence microscopy.
