Functional surfaces that are microbiologically effective. temicon produces nano- and microstructures, e.g. based on the lotus flower. The replicated lotus effect on the microstructured surface can prevent the attachment of bacterial microorganisms. Or as structures similar to shark skin (riblet structures) that reduce drag on airplanes, ships and windmills. A moth’s eye has nanostructures on its surface that are used for antireflective treatment of surfaces. Nature provides a variety of solutions in the field of micro- and nanostructured surfaces.
