During the last years, research in surfaces with antibacterial properties has been of great interest in order to reduce formation of bacterial biofilms. Biofilms are complex structures highly resistant to diverse bactericidal agents, involved in severe damage to industrial settings, contamination of medical devices and chronic infections. Several organisms have self-nanostructured surface properties to protect themselves against infections. Recently, mimicking nature, high aspect ratio nanoprotrusions have been applied as mechanical bactericidal surfaces independent of chemical composition. Considering the fore mentioned, the goal of this work was to develop a novel nanostructured surface based on silicon and to test its bactericidal activity.
