Recent progress in electrochemical biosensors for the detection of alpha-fetoprotein as the biomarker of liver cancer

Alpha fetoprotein (AFP) is one of the clinical tumor biomarkers commonly used in the diagnosis of primary liver cancer. Electrochemical biosensor has the advantages of high analysis speed, low cost and high sensitivity. It is usually used to analyze and detect various cancer markers. In recent years, many electrochemical biosensors for AFP detection have been reported, which made an important contribution to the diagnosis of primary liver cancer. This paper reviews the latest progress of electrochemical biosensors for the detection of AFP as the biomarker of liver cancer.
