Abstract
In the talk several new pathways for the synthesis of surface-attached ultrathin polymer layers attached
to surfaces of different chemical compositions, i.e. biological, polymeric and oxidic surfaces, will be
described. Examples are the generation of polymer brushes through growth polymer molecules at the
surface of the substrate in situ, the photolinking of molecules to surfaces and the generation of thin
surface-attached networks. Through choice of appropriate reaction conditions and (co-)polymer
composition surfaces with precisely tailored properties can be obtained. Special emphasis will be
placed on systems in which the polymers carry functional groups so that they can be used in sensor
applications. The application of the obtained surface-attached layers for areas such as DNA-chips and
microfluidic devices will be described.
