▎ 摘　　要

NOVELTY - The sensor has a molybdenum electrode, a reference electrode and a saturated electrode bonded together by chemical bond using gold electrode graphite alkene quantum point. USE - Graphene quantum dot modified electrochemical sensor i.e. three-electrode system sensor, for detecting concentration of hydrogen peroxide to diagnose reactive oxygen species disease. ADVANTAGE - The sensor measures linear range of hydrogen peroxide concentration of 2 micrometer-8 mm in upper limit and lower limit of 1.3 micrometer in real time and provides quick response. The sensor has wide detection limit and wide application range. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene quantum dot modified electrochemical sensor manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating relationship between voltage and current of a graphene quantum dot modified electrochemical sensor.
