  • Patent number: 10598624
    Abstract: Embodiments of the present disclosure relate to electrochemical analyte sensor electrodes that have one or more sensing structures, each structure has a respective perimeter at least partially around it to define the structure so that each of the structures have a liquid limiting barrier around their perimeters. The liquid limiting perimeter may completely or partially encompass the perimeter of each sensing structure of the electrode. Also provided are methods for fabricating the electrodes, analyte sensors employing the subject electrodes, and methods of using the analyte sensors in analyte monitoring.

  • Patent number: 6800488
    Abstract: Methods for making reagent test strips are provided. In the subject methods, a test strip precursor made up of an elongated support material having a planar surface and a narrow stripe of reagent material positioned along its central axis is cut according to an inter-digitating pattern to produce the plurality of reagent test strips. The initial precursor material may be a tape or in the form of a card. Also provided are the reagent test strips produced by the subject methods and kits that include the same. The subject reagent test strips and kits find use in analyte detection and/or concentration determination assays.
