Abstract

The invention discloses a preparation method of a copper nanowire graphene composite-modified electrode, as well as applications thereof serving as a glucose electrochemical sensor. The preparation method mainly comprises the following steps: modifying ITO glass as an electrode by utilizing a copper nanowire graphene composite, preparing the copper nanowire graphene composite by adopting liquid phase reduction, evenly mixing with a Nafion solution, dropwise adding to the ITO glass, to obtain the copper nanowire graphene composite. The sensitive quantitative analysis determination can be performed to glucose by adopting a current-time curve through the electrochemical catalysis oxidization action of the modified electrode to the glucose. The preparation method is simple and easy, low in detection limit, and high in sensitivity, and the concentration of glucose can be fast detected.

Description

technical field

[0001] The invention belongs to the technical field of electrochemical analysis and detection, and relates to the preparation of a copper nanowire-graphene composite modified electrode and its application as a glucose electrochemical sensor. Background technique

[0002] Diabetes is a metabolic disorder syndrome that belongs to the world public health problem. Once diabetes is not well controlled, it can cause many complications. These complications can be greatly reduced or even eliminated by strictly controlling the blood sugar concentration level of the human body. Glucose electrochemical sensors can be divided into enzyme and non-enzyme according to the use of enzyme. Compared with enzyme-based glucose sensors, non-enzymatic glucose sensors have the advantages of not being limited by oxygen concentration, better stability, and low cost, so they have received great attention.
