Patent number: 8992590Abstract: 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.Type: GrantFiled: July 31, 2009Date of Patent: March 31, 2015Assignees: Fraunhofer-Gesellschaft zur Forderung der Angewandten Forschung E.V., Bio-Gate AGInventors: Matthias Ott, Ingo Grunwald, Dirk Salz, Michael Wagener, Klaus-Dieter Vissing, Wolfgang Hielscher, Christopher Dölle
