The application of electrochemical immunosensors in laboratory diagnosis

Electrochemical immunosensors is widely used in clinical laboratory diagnosis for its unique properties such as cost-effective, rapid, sensitive and specific and play a role in POCT and rapid diagnosis. This paper introduces the principle and advantages of electrochemical immunosensor. Biological molecules such as tumor marker, myocardial marker, hormone, pathogenic bacteria, viruses, and autoimmune antibody has carried on the induction, based on the domestic and foreign research results. The advantages and disadvantages of electrochemical immunosensor was evaluated, and the research on its application prospect is analyzed.(Chin J Lab Med, 2017, 40: 894-897) Key words: Electrochemical techniques; Immunoassay; Biological markers; Clinical laboratory techniques; Nanostructures
