  • Antibacterial coating or surface comprising vertical, standing angstrom scale flakes
    Patent number: 11414552
    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.
    Type: Grant
    Filed: February 11, 2021
    Date of Patent: August 16, 2022
    Assignee: DENTSPLY IH AB
    Inventors: Martin Lovmar, Santosh Pandit, Venkata R. S. S. Mokkapati, Jie Sun
