Ochratoxin A(OTA) is a secondary metabolite originated from fungi penicillium and aspergillus,which is widely distributed in nature,with various strong toxicities such as hepatotoxicity,nephrotoxicity,carcinogenic and mutagenic effects.Considering these potential toxic effects of OTA,the International Agency for Research on Cancer(IARC) has classified it as a human carcinogen(Ⅱ B).Therefore,how to develop OTA detection methods with high sensitivity have arouse wide attention.The development and applications of electrochemical sensors for OTA detection for the past 10 years are summarized in this paper.Based on different identification elements,the main types of OTA electrochemical sensors,adaptor and immune sensing,and the advantages and disadvantages of the corresponding sensings are described.The prospect for the future development of OTA electrochemical sensors is put forward.This review provides a certain reference for the further research and application of OTA electrochemical sensors.
