From cicada to implant – bionic-inspired materials research

Infection protection has many facets. Metals with antibacterial effects are one of them for some years now. Nanostructured surfaces that kill bacteria are a younger development. Prof. Manfred Köller from the German university hospital Berufsgenossenschaftliches Universitätsklinikum Bergmannsheil in Bochum explains in our video how nanopillars destroy bacteria. We also ask Prof. Alfred Ludwig from the Ruhr-Universität Bochum how theses pillars are grown on titanium tiles in his lab and what cicada wings have to do with this.
