Roughness and wettability assessment of substrates with regard to cell adhesion — •Paul Lühe, Issam Assi, Christian Völkner, Regina Lange, Ingo Barke, and Sylvia Speller — Institute of Physics, University of Rostock, 18051 Rostock

Cell adhesion and spreading on surfaces are crucial properties for medical applications, e.g. for biocompatibility of human implants. Important parameters frequently considered in this context are wettability and roughness, both being dependent on geometric and chemical details of the surface, including the history of preparation and treatment. Common techniques for surface conditioning are rinsing and ozone cleaning. In this study we assess the effect of treatment and exposure time in ambient conditions on roughness and wettability of glass with and without transparent Au layers and PDMS surfaces by means of contact angle measurement and atomic force microscopy. The results are discussed in view of expected cell adhesion and spreading properties.
