Abstract
The invention refers to coatings on different substrates, whereby a hydrophilic polymer layer is bound by means of a polymer adhesion promoter layer to a substrate. A method for the production of these layer systems is disclosed as well. The layers according to the invention can be used as immobilization matrix and for the suppression of non-specific protein adsorption in biosensors, MALDI targets and other bioanalytical devices. Furthermore they can be used for the bio-compatibilization of implants and for the coating of contact lenses. Optical elements, which are provided with such coatings, do not fog up any more. Beyond that the layers are dirt-deflecting and/or self-cleaning.
Claims20
A coating, comprising:
- a substrate;
- a polymeric adhesion promoter covering said substrate, the covering of said polymeric adhesion promoter is such that it comprises one of:
- a covering parallel to the surface or a covering partly flat on the surface of the substrate, and partly loop-like covering relative to said substrate;
- and
- one further hydrophilic polymer layer, containing at least one polymer with a plurality of reactive groups, whose polymer chains are at least partially arranged brush-like, which is attached to said polymeric adhesion promoter, said at least one polymer of said further hydrophilic polymer layer being arranged, for the most part, vertically to said substrate, and having a plurality of functional groups attached.
