Biosensors for Aflatoxins Detection in food industrial

Mycotoxins are secondary metabolites that mould produce naturally. Due to their ubiquitous presence in foodstuffs and their potential risk for human health, prompt detection isimportant. It is estimated that approximately 25% of the world’s crops are contaminated to some extent with mycotoxins. Some mycotoxins(e.g.,aflatoxins) have been designated biowarfare agents due to their potential Carcinogenicity.Aflatoxinsare highly toxic andcarcinogenic secondary metabolites produced mainly by three anamorphic species of the genus Aspergillus: A. flavus, A. parasiticusandA. nomius.A biosensor is an analytical devicefor the detection of an analyte that combines a biological component with a physicochemicaldetector component. The most commune biosensor scheme is reported in Fig.2 and it is consists of 3 parts. Biosensor assays are rapid, easy to perform, and inexpensive and could beadvantageous in comparison with ELISA or GC/MS for analysis on food, but in our opinion,further improvements of analytical parameters such as precision, accuracy, and detection limits (especially for Aflatoxins biosensor applications) are required.The two types of biosensors are SPR and QMC
