Within a few seconds first of all unspecific proteins adsorb on the surface of materials from the surrounding environment. These proteins then modify the degree of adhesion of bacteria and cells.
We can equip surfaces wet-chemically or by means of plasma technology so that the protein adsorption is controlled. As a result we are in a position to control an increase or a decrease of the adsorption as well as the selective adsorption of certain proteins and their orientation relative to the surface.
This, among other things, is of great importance for cell adhesion in tissue engineering.
