Latest Patents

Pritchard holds a patent for an electrochemical biosensor test strip. This test strip requires a minimum blood sample volume of about 9 microliters. It features working and counter electrodes that are of the same size and made from the same electrically conducting material, placed on a first insulating substrate. A second insulating substrate overlays the electrodes, which includes a cutout portion that forms a reagent well. This design exposes a smaller area of the counter electrode than the working electrode. The reagent for analyzing an analyte substantially covers the exposed areas of both electrodes in the reagent well. Additionally, a spreading mesh impregnated with a surfactant overlays the reagent well and is affixed to the second insulating substrate. The small cutout portion measures 4 millimeters by 4.2 millimeters, while the mesh measures 6 millimeters by 5.8 millimeters. The small amount of reagent, 4 microliters before drying, allows the test strip to analyze a whole blood sample of about 9 microliters.
