Aflatoxin is a kind of biotoxins with acute toxicity and strong carcinogenicity. Quick and accurate analysis is one of the most effective methods to minimize or avoid its hazard. Electrochemical biosensor has drawn widespread attention of domestic and foreign researchers for aflatoxin analysis,due to its rapidity,high degree of sensitivity and specificity,combined with its easiness to be miniaturized. So far,immunosensor, enzyme sensor,and DNA biosensor have been applied to electrochemical biosensing of aflatoxin. In this paper, the research progress of different kinds of sensors for aflatoxin analysis is reviewed. The importance of new materials and advanced technologies for immunoassay of aflatoxin is particularly highlighted. Main problems and trends in electrochemical biosensing of aflatoxin are discussed and prospected. |
