%X Aflatoxins are naturally occurring mycotoxins that are produced by many species of Aspergillus, a fungus, most notably Aspergillus flavus and Aspergillus parasiticus. Aflatoxins are toxic and among the most carcinogenic substances known. They arenĄ¯t destroyed by thermal procedures. Quartz Crystal Microbalance is an ultrasensitive piezoelectric method for detection of aflatoxin in concentrations under the value 4 ng/ml (ppb) ¨C current maximum permitted levels set by European Commission. In this method, the quartz crystal surface was coated with a self-assembled monolayer of ethanethiol. Aflatoxins B1 and M1 were diluted in methanol. To obtain the calibration curve, several samples with various concentration of aflatoxin were measured.
