Micro- and Nanostructured Materials – Combining Shape, Size and Chemical Functionality

The aim of our research is to use micro- and nanostructuring techniques to create polymer surfaces with defined topologies for biomedical applications. Using methods like colloidal lithography, electron beam lithography, dip-pen lithography or contact printing, we first generate micro- and nanopatterns on surfaces. These are then used as selective anchoring sites for polymers or initiating sites for polymerization reactions. We use numerous techniques for the characterization of such surfaces, among them atomic force microscopy, ellipsometry, and surface plasmon resonance. Further, biological assays are used to investigate the biocompatibility of our materials.
