Abstract
A new optical biosensor has been developed for detecting and quantifying aflatoxins that are commonly found in a variety of agricultural products. In the biosensor we use a high-tech semiconductor material – silicon for the efficient high-accuracy registration of narrow spectral bands or specific wavelengths. On its base, we develop a structure with two oppositely directed potential barriers. The total current conditioned by these barriers depends both on the external voltage and on the wavelength of the absorbed radiation. It is possible to modify these parameters and obtain high-accuracy data on mycotoxic contaminants in food and provender in natural conditions.
