    Area of Science:

    • Electrochemistry
    • Biosensors
    • Analytical Chemistry

    Background:

    • Amperometric glucose sensors are vital for diabetes management.
    • Interference from physiologic coreactants can affect sensor accuracy.
    • Platinum-based electrodes are commonly employed in electrochemical sensing.

    Purpose of the Study:

    • To evaluate the influence of physiologic coreactants on a (Pt-pvc) Pt electrode.
    • To assess the sensitivity and interference resilience of the amperometric glucose sensor.
    • To determine the feasibility of the sensor for in vivo blood glucose monitoring.

    Main Methods:

    • Current-voltage scans were performed on a (Pt-pvc) Pt electrode.
    • The electrode's response to glucose in the presence of interfering substances was measured.
    • Preliminary in vivo measurements were conducted.

    Main Results:

    • The (Pt-pvc) Pt electrode demonstrated sufficient sensitivity to glucose.
    • Significant interference from tested substances was observed but did not negate glucose detection.
    • Preliminary in vivo tests indicated potential for monitoring.

    Conclusions:

    • The amperometric glucose sensor exhibits robustness against interfering physiologic coreactants.
    • Proper pretreatment enables the use of this sensor for short-term blood glucose monitoring.
    • Further development may enhance its clinical applicability.
