Rene Beutner has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Metallic object with a nucleic acid coating and derivatives thereof and method for producing said object
    Patent number: 7585965
    Abstract: A metallic object has a coating made of a thin metal oxide layer and nucleic acids or nucleic acid derivatives bonded thereto. The nucleic acid compounds have 5?-terminal or 3?-terminal molecule areas that are incorporated stably into the metal oxide layer. The unincorporated areas of the nucleic acid compounds that are not incorporated into the metal oxide layer are freely accessible for subsequent interactions with other molecules such as complementary nucleic acids having active ingredients attached thereto.
    Type: Grant
    Filed: July 4, 2003
    Date of Patent: September 8, 2009
    Assignee: Technische Universitä{umlaut over ( )}t Dresden
    Inventors: Dieter Scharnweber, René Beutner, Sophie Roessler, Thomas Hanke, Hartmut Worch, Bernd Schwenzer, Jan Michael

  • Chitosan-coated metallic article, and process for the production thereof
    Publication number: 20050079198
    Abstract: The invention describes an article made from chitosan-coated metal, where an impermeable chitosan layer having a barrier action is present on the metal through electrochemical polarisation in a chitosan-containing solution. The incorporation of biologically active components into the chitosan coating enables the coating to be matched to various applications and the bio-compatibility of correspondingly modified surfaces to be increased. Metallic articles or surfaces coated in this way are used, for example, as material for medical implants.
