  • Plasma-aided treatment of surfaces against bacterial attachment and biofilm deposition
    Patent number: 6096564
    Abstract: Passivation of bacterial biofilm exposed surfaces is carried out utilizing cold-plasma treatments. Exposure of a substrate with biological contamination thereon to an oxygen plasma sterilizes and cross-links the biological contamination into a form which is resistant to further adhesion of bacteria and other biomaterials while cleansing and sterilizing areas of the substrate that are not covered by the biofilm. A second step may be carried out to plasma mediate the deposit of an anti-fouling film using components that will provide macromolecular networks on the substrate with a desired structure which is resistant to bacterial adhesion.
