From Computer Hard Disks to DNA-chips: Tailor
Instituto de Estructura de la Materia, C.S.I.C. Seminario de Física Macromolecular, Instituto de Estructura de la Materia, CSIC From Computer Hard Disks to DNA-chips: Tailor-made Surfaces for Microsystems Engineering Prof. Dr. Jürgen Rühe University of Freiburg - IMTEK Department of Microsystems Engineering Laboratory for Chemistry and Physics of Interfaces Georges-Koehler-Allee 103 / Rm 00 109 D-79110 Freiburg, Germany Día: Viernes 8 de Septiembre, 2006 Hora: 12:00 Lugar: Sala 215 Instituto de Estructura de la Materia CSIC Serrano 119, Madrid, 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.
