  • Mass-sensitive biosensors
    Patent number: 6087187
    Abstract: The present invention relates to a piezoelectric sensor for use in diagnostic and analytic processes, in particular for the immunochemical detection of diagnostically relevant specific binding partners.
    Type: Grant
    Filed: December 20, 1996
    Date of Patent: July 11, 2000
    Assignee: Dade Behring Marburg GmbH
    Inventors: Andreas Wiegand, Norbert Madry, Carsten Schelp, Paul Meller, Michael Mohlen
  • Method for stabilizing hydrolysis-sensitive molecules or molecular moieties
    Patent number: 6010868
    Abstract: The invention concerns a method of stabilizing molecules, or parts of molecules, which are sensitive to hydrolysis, in particular hydrolysis-sensitive labels or label-containing tracers in aqueous solutions. The invention also concerns kits for carrying out immunological assays making use of the method proposed.
    Type: Grant
    Filed: December 20, 1996
    Date of Patent: January 4, 2000
    Assignee: Behring Diagnostics GmbH
    Inventors: Stephan Neuenhofer, Reinhard Kasmarker, Gotz Walter, Hans-Peter Harthus, Gunther Nau, Heinz-Jurgen Skrzipczyk, Peter Molz, Norbert Madry
  • Biosensor
    Patent number: 5892144
    Abstract: A biosensor (10) for measuring changes in viscosity, density and/or mass in a fluid to be examined, for example a blood coagulation sensor or immunoassay system. According to the invention, the reagents necessary for the test are contained in a support (13) which is put onto the measurement surface (18) of a piezoelectric element (8). As a blood coagulation sensor, the measurement surface (18) may according to the invention itself have a coagulation activator action or else be coated with coagulation activators.
