Description

Full text: Surface chemistry, wettability and nanotopography are important features for materials used in bioapplications as they strongly influence cell-substrate interactions. We investigated the influence of two types of photomodification on polystyrene (PS) foils and Petri dishes, for bioapplications. Photomodification was done with a UV Xe2* excimer lamp (172 nm) and with KrF laser (248 nm) for periodic surface structures (LIPSS). Contact angle and XPS measurements shown an improvement in wettability and a significant change in surface chemistry in both cases. Cell seeding experiments indicate that photomodified PS strongly influence cell adhesion, proliferation and orientation. (author)
