  • Microelectrodes and amperometric assays
    Patent number: 5635054
    Abstract: A photo-ablation technique is used to create apertures (4) in a layer (2) of electrically insulating material and allow electrically conducting material (3) exposed through the apertures to create a microelectrode. The microelectrode can be used for assay methods and in an assay unit.
    Type: Grant
    Filed: March 6, 1995
    Date of Patent: June 3, 1997
    Assignee: Ecossensors Limited
    Inventors: Hubert H. J. Girault, Brian J. Seddon
  • Method of making gas permeable membranes for amperometric gas electrodes
    Patent number: 5575930
    Abstract: A method of manufacturing a gas-permeable membrane for an amperometric gas electrode comprising demetallizing areas of a metallized film to obtain a regular array of gas-permeable micropores.
    Type: Grant
