All interactions of materials with their respective environments are controlled by the topography and chemical composition of their surfaces. Examples are the adhesion between two objects, wetting of surfaces by contacting liquids and the adsorption of molecules from the surrounding medium. Accordingly, it is important to develop chemical tools which allow the attachment of tailor-mode polymer molecules to surfaces of different chemical composition. In the presentation a new strategy will be presented which allows generating novel, micropatterned polymer coatings with tailor-made properties with high spatial resolution on a variety of different substrates, ranging from inorganic surfaces to polymers and biological materials]. We combine this chemical toolbox with the formation of very distinct micro- and nanostructures yielding novel metamaterials. We show some examples how such designed surfaces can be used to control the wetting properties of surfaces, determine adhesion of cells to artificial surfaces or prevent the formation of biofilms on surfaces. We give examples how the surface properties of materials can be adapted according to an external stimulus and describe how the obtained materials can be used for the generation of materials with extremely unusual wetting properties or new bioanalytical devices, such as DNA, RNA, protein or polysaccharide chips
