[A portable sensory system for phenols detection based on molecular-imprinted polymers with catalytic properties].

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.

[Aflatoxin-selective molecularly-imprinted polymer membranes based on acrylate-polyurethane semi-interpenetrating polymer networks].

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.
