Abstract
Permanently substituted oxyfluorinated surfaces can be formed on non-fluorinated substrates having a fluorinated surface or fluorocarbon coating applied by gas phase surface fluorination or plasma deposition. The oxyfluorinated surfaces can be refunctionalized by bonding organosilanes, isothiocyanate-containing fluorescent compounds and proteins, such as enzymes, antibodies and peptides directly to such surfaces. Surfaces refunctionalized with such protein based groups are useful in the fabrication of biological sensors, devices for separation of cell lines, filtration applications for selective binding of antigens. Masking techniques can be employed in forming a predetermined pattern of covered and exposed surfaces, for example, prior to oxyfluorination.
