Abstract: An antibacterial device is disclosed that includes a substrate and an antibacterial coating or antibacterial surface being provided on at least a part of the substrate's surface. The antibacterial coating or surface includes Angstrom scale flakes, where the Angstrom scale flakes are arranged in a standing position on the substrate surface and are attached to the substrate surface via edge sides thereof. The Angstrom scale flakes can, for example, be graphene flakes, or graphite flakes having a thickness of a few atom layers. It has been found that such standing flakes are efficient in killing prokaryotic cells but do not harm eukaryotic cells.

Abstract: An article having an antibacterial surface having an antibacterial surface having the nano scale flakes or platelets arranged essentially aligned to each other and extending out from said surface with a length in the range of 0.5-30 microns. The antibacterial surface is produced by processing a mixture of a polymer matrix material and a filler material comprising the nanoscale flakes or platelets by pressing the mixture through a die while heated to a temperature above a melting temperature of the polymer matrix material. Hereby, the nano scale flakes or platelets become aligned, with their longitudinal directions being oriented in substantially the same direction. A surface of the processed mixture which is oriented essentially perpendicularly to the longitudinal directions of the nano scale flakes or platelets is then etched or ablated to partly expose the nano scale flakes or platelets, thereby making the surface antibacterial.
