  • TEST SENSORS AND METHODS OF USING THE SAME
    Publication number: 20190249214
    Abstract: A reagent composition containing GDH-PQQ as an enzyme-co-factor and screen-printed on working and counter electrodes of electrochemical biosensors, maintains activity of the enzyme reagents by proper selection of components. A preferred composition includes hydrophilic polymers, amorphous untreated silica, buffers, surfactants, and a mediator.
    Type: Application
    Filed: April 24, 2019
    Publication date: August 15, 2019
    Inventors: Amy H. Chu, Hope G. Spradlin
  • Method of Screen Printing On a Substrate
    Publication number: 20150104561
    Abstract: A test sensor reagent for measuring the concentration of analytes in body fluids includes cellulose polymers for improving the stability of the test sensor and reducing the total assay time. The test sensor reagent also includes an enzyme, an electron transfer mediator and a rheological additive.

  • Reagent composition for electrochemical biosensors
    Patent number: 8921065
    Abstract: A reagent composition containing GDH-PQQ as an enzyme-co-factor and screen-printed on working and counter electrodes of electrochemical biosensors, maintains activity of the enzyme reagents by proper selection of components. A preferred composition includes hydrophilic polymers, amorphous untreated silica, buffers, surfactants, and a mediator. For example, the biosensor is useful in the amperometric determination of glucose.
