Portable devices for the express control of the phenols content in water were developed. Polymers mimicking active site of the enzyme tyrosinase, synthesized using the method of molecular imprinting, were obtained by co-polymerization of the complex Cu (II)-catechol-urocanic acid ethyl ester with ethyleneglycoldimethacrylate. Concentration of phenols in the analyzed samples was detected using universal portable device oxymeter with the oxygen electrode in a close contact with catalytic molecularly-imprinted polymer as a transducer.

lymer membranes, synthesized using acrylamide as a functional monomer, were characterized by sufficient mechanical stability and high adsorbtion capability towards aflatoxin B1. The molecularly-imprinted polymer membranes were characterized by the pronounced imprinting effect as well as by insignificant adsorbtion of aflatoxins B2 and G2. Therefore, the synthetic analogues of bioreceptors able to individual recognition of aflatoxin B1 were obtained and used as a basis for the optical sensor system for aflatoxin B1 detection in a concentration range 1-500 ng/ml.

Synthetic analogs of biological receptors able to group-selective recognition of aflatoxins were obtained using the combination of the technique of molecular imprinting with the method of computer modeling. The synthetic receptors were obtained in a form of thin and porous membranes based on semi-interpenetrating polymer networks. The selection of functional monomers able to noncovalent interactions with aflatoxins B1, B2, and G2 was based on the data of computer modeling.

A capacitive sensor for environmental monitoring based on thin films of desmetryn-selective molecularly imprinted polymer (MIP) was developed. The method of modification of gold electrodes with the thin film of herbicide-selective MIP using the grafting polymerization approach was developed. The method of computational modeling was used to optimize the composition of desmetryn-selective MIPs.
