Practical procedures according to the self-assembling principle are used to modify a number of substrate materials such as glass, silicon, gold, metals/oxides, polymers (e.g. polystyrene), implant materials (polydimethylsiloxane, polyhydroxyethylmethacrylate, polymethylacrylate, poly-L-lactate) for a wide range of (bio)functional applications based on self-assembled monolayers of structural-designed derivatives of a novel aminocellulose type with varying (bio)functional surface properties and special amino(organo)polysiloxanes. By microcontact printing, lateral structural patterns are stamped onto the substrate material surfaces in the form of monolayer composites of aminocellulose chains and amino(organo)polysiloxanes.
