FORMATION OF SURFACELY PROGRAMMED, CHEMICAL CREATED SITES AND WAYS OF ESTIMATION OF THEIR SELECTIVITY TO DIFFERENT MYCOTOXINES

Abstract
The problem of mycotoxins as potential food contaminants has become widespread in violation of the requirements of intensive processing technologies for agricultural crops and the loss of plant resistance to phytopathogens. Growth in the content of mycotoxins in food is also directly related to the uncontrolled use of nitrogen fertilizers and pesticides. The article presents experimental studies on the search for the most effective ways of forming selective chemical sites aimed at quantifying individual mycotoxins using sensory technology. It has been established that the registration of the formation of the corresponding specific complex can be carried out potentiometrically and optically on the basis of the PPR principle. It was revealed that when registering the specific complex created for and using the PPR principle, the transducer surface must be pretreated with PAA. A tried-and-true method of forming selective matrix-programmed surfaces can be recommended for the sake of terrestrial transducer surface sensors aimed at screening mycotoxins among environmental objects. It is determined that the surface structures programmed can be restored for reuse by washing them with acetonitrile or methanol. When reused more than 10 times the specific signal changes only within 10%.
