▎ 摘　　要

NOVELTY - The device has a reaction chamber whose bottom surface is provided with a silicon wafer, which is fixed with a single graphite layer of a working electrode. The working electrode is provided with a pair of electrodes and a reference electrode, where the working electrode is equipped with a three-electrode system. The three-electrode system is provided with a magnet, which is located on a silicon chip, and the pair of electrodes and the reference electrode are located on the silicon wafer. USE - Working electrode single-layer graphene nano-particle detecting device. ADVANTAGE - The device realizes high speed conduction electrons by modifying nano-gold and magnetic beads so as to amplify a signal and realize high sensitivity nano-particle detection. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for detecting single-layer graphene nano-particle of a working electrode (2) a kit. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical illustration of a method for detecting a single-layer graphene nano-particle of a working electrode.
