Wet-chemical processes

Depending on the surface chemistry of a material, available functional groups are used and biomolecules such as proteins, DNA or polysaccharides are bound covalently. First of all the biomolecules are chemically derivatized, as required. For example, surfaces of acrylate implants are coated with thiol-modified heparin in a targeted way to permit colonization with endothelial cells.

We activate materials that do not provide any functional groups as a target by means of various gas phase processes, thus introducing specific functional groups.
