Optical sensor for the detection of mycotoxins
The methods of detection of mycotoxins in agricultural products have been
analyzed. The advantages of using the fluorescence methods for the express diagnostics of
the presence of mycotoxins in samples have been shown. The development of an optical
biosensor, which allows the detection of mycotoxins in the field, has been presented. The
principles of operation have been established, and the constructive solution of a sensor has
been proposed. An electro-optical scheme for obtaining an information signal has been
developed and tested. The particular attention has been paid to the choice of an element
base of the proposed microsensor. The principles and procedure for its validation have been
shown. The practical results of testing the developed technical solution have been
presented. The achieved relative error in the linear approximation of the sensor conversion
characteristics in the interval of concentrations 0...100 ppb at a temperature of 15...25 Β°Π‘
does not exceed 2%. The developed sensor can be used in agriculture for the express
detection and evaluation of the mycotoxin contamination
