Abstract

The present invention relates to the use of a crosslinked, silicon-containing layer containing, substantially consisting of or consisting of silicon, O, C, H, optionally N which can be produced by plasma polymerization and/or crosslinking of organosilicon liquids by a plasma process and/or UV radiation of a wavelength of less than 250 nm, without using metals of an atomic number of more than 14, as a biocompatible surface, for imparting to a surface or providing a surface with a non-genotoxic effect. The invention also relates to correspondingly coated articles and to processes for the production thereof.
