In the area of "antimicrobial metallic surfaces" contact materials with active antibacterial properties are investigated and developed. In this way, transmission of infections and biofouling, which can lead to damage to technical systems in the form of biological deposits and corrosion, are to be reduced. In this context, the groups research is focused on biochemical mechanisms with respect to kill germs on metallic surfaces. Based on this research activity, the antimicrobial performance of the materials should be increased and optimized for specific application fields. Especially in the space sector, antimicrobial surfaces can contribute to the safety of astronauts. For this reason, the effects of such surfaces are currently being investigated together with ESA and NASA. The interaction between germ and material is defined, among other things, by its surface, which is specifically modified by laser techniques such as DLIP and Direct Laser Writing.
