Patents by Inventor Peter Damien John Osman

Peter Damien John Osman 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).

  • Composite membrane sensor
    Patent number: 6740213
    Abstract: The present invention provides a biosensor comprising an electrode and a membrane in which the biosensor includes at least two zones each zone differing from each other zone in a property. The membrane includes a plurality of ionophores, at least a proportion of which are capable of lateral diffusion within the membrane. A plurality of first binding partner molecules are attached to membrane elements positioned within a first zone such that the first binding partner molecules are prevented from diffusing laterally into a second zone. Second binding partner molecules are attached to the ionophores and the rate of lateral diffusion within the membrane of the first binding partner molecules and second binding partner molecules is different.
    Type: Grant
    Filed: January 16, 2001
    Date of Patent: May 25, 2004

  • Ionic reservoir through application of an electrical potential
    Patent number: 6451196
    Abstract: An improved membrane based biosensor incorporates sensing and reference electrodes and a dc electrical potential produced by a counter electrode. The biosensor incorporates ionophores. The conductivity of the membrane is dependent on the presence or absence of an analyte. A functional reservoir exists between the sensing electrode and a lipid membrane deposited on the sensing electrode. The invention also includes the method of detecting the presence or absence of the analyte by use of the biosensor.
