▎ 摘　　要

NOVELTY - The electrochemical sensor has a reference electrode (3), a counter electrode (2), a dual working electrode (1), and a substrate (4) for fixing the electrode. The substrate is provided with a liquid filling hole (5). The dual working electrode includes a modified electrode (101) having a surface modified with a platinum-graphene oxide nano material coating and an unmodified bare electrode (102). The platinum-graphene oxide nano material coating layer is formed by dropping a platinum-graphene oxide nano material solution on the surface of the electrode and drying. The precursor of platinum is potassium tetrachloroplatinate. USE - Fructose non-enzymatic electrochemical sensor used in medical and food industries. ADVANTAGE - The self-reference recording method adopting the double working electrode mode reduces the influence of the interference substance on the detection result of fructose while detecting fructose, and provides a quicker method for detecting fructose in the medical and food industries. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of detecting fructose using a fructose non-enzymatic electrochemical sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a fructose non-enzymatic electrochemical sensor.
