Abstract
The invention concerns a process for coating a metallic or semimetallic surface in which coating molecules containing reactive groups are bound covalently to the surface by irradiation with light and it also concerns a structured coated surface.
Claims13
A coated object comprising a metallic or semimetallic surface with an arrangement of coated and uncoated areas and the coated areas are miniaturized, wherein the coated areas are the same and comprise coating molecules covalently bound to the metallic or semimetallic surface in the form of a monolayer, wherein the coating molecules contain groups that are covalently bound to the metallic or semimetallic surface only by irradiation with light, wherein the groups of the coating molecules are selected from C═C or C═O double bonds and wherein the coated object is a biosensor.
A coated object comprising a metallic or semimetallic surface with an arrangement of coated and uncoated areas and the coated areas are miniaturized, wherein the coated areas are the same and comprise coating molecules covalently bound to the metallic or semimetallic surface in the form of a monolayer, wherein the coating molecules contain groups that are covalently bound to the metallic or semimetallic surface only by irradiation with light, wherein the coating molecules contain at least one additional functional group in addition to the groups covalently bound to the surface, wherein the coating molecules contain conjugated π-systems as the additional functional groups and wherein the coated object is a biosensor.
