摘要
赭曲霉毒素A(Ochratoxin A,OTA)是一种由赭曲霉、青霉菌等真菌产生的次级代谢产物,在自然界分布广泛,具有肝毒性、肾毒性、致癌、致突变作用。鉴于其危害的严重性和污染的广泛性,发展高灵敏度的OTA检测技术引起了研究者的广泛关注。该文阐述了近年来新型电化学传感技术在OTA检测方面的发展及应用,全面综述了目前OTA电化学传感器的主要类型及其优缺点,并对其发展方向提出了展望,从而为基于OTA的电化学传感器的深入研究与应用提供了参考。
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(ⅡB).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.
