  • Low cost electrochemical disposable sensor for measuring glycated hemoglobin
    Patent number: 8702931
    Abstract: Design of a disposable screen printed electrode (SPE) for sensing percentage glycated hemoglobin using electrochemistry is disclosed. SPE has four electrodes, one working electrode for the detection of glycated hemoglobin, one working electrode for the detection of hemoglobin and the other two electrodes are counter and reference electrodes that are common for both detection schemes. It also has a cellulose acetate membrane with lysis agents and surfactant embedded in it. Lysis agents lyse erythrocytes and release hemoglobin. Surfactants modify hemoglobin structure and enhance the rate the electron transfer and thereby the output signal during the electrochemical analysis. The SPE is low cost and user friendly. The only input from the user is a drop of blood.
