英文摘要:

      Electrochemical sensor has the advantages of low cost, high sensitivity, good selectivity and high efficiency. It has been widely used in the field of food analysis and detection. Graphene has become an ideal material for constructing electrochemical sensor because of its large specific surface area, wide electrochemical window and fast electron migration rate. This paper searched the research on graphene electrochemical sensors in food detection published in Web of Science English database and HowNet Chinese database in recent 3 years, reviewed the characteristics and preparation methods of graphene and its derivatives, and introduced the research progress of electrochemical sensors based on graphene materials in food analysis and detection. On this basis, the future application of graphene electrochemical sensor in the field of food analysis and detection was prospected from the aspects of optimizing doping materials, studying the interaction mechanism between electrode materials and tested objects, designing and manufacturing electrode materials, so as to provide references for the development of graphene electrochemical sensor in the field of food detection.
