Highly stable, protein resistant thin films on SiC-modified silicon substrates.

Thin films terminated with oligo(ethylene glycol) (OEG) could be photochemically grafted onto ultrathin silicon carbide layers that were generated on silicon substrates viacarbonization with acetylene at 820 °C. The OEG coating reduced the non-specific adsorption of fibrinogen on the substrates by 99.5% and remained resistant after storage in PBS for 4 weeks at 37 °C. [ABSTRACT FROM AUTHOR]
