  • Search for new matrices in molecular imprinting to improve imprinting factors and selectivity of rebinding templates.

Some resutls of the group of Dr. Mikhail Beklemishev

The "fluorescent tongue" technique is based on the use of a blend of fluorophores of various nature emitting over a wide range of spectrum and changing the emission intensity to a different extent in the presence of different analytes. In the pilot feasibility study we prepared a blend of up to 5 fluorophores covering the emission range of 360–800 nm: quantum dots CdSe/CdS/ZnS and PbS, a Schiff base produced from o‑phthalic dialdehyde and polyethyleneimine, and fluorescein and rhodamine B attached to silica nanoparticles. We showed that the attachment of the fluorescent dyes to a nanoadsorbent appreciably increased their responsiveness to quenching/dequenching by organic compounds. As model analytes, we used 4 compounds (amikacin, sulfamethoxazole, piracetam and chloramphenicol) and their mixtures in equal concentrations. To evaluate the discrimination ability of the fluorophore blends, their fluorescence spectra obtained in the presence of the model analytes were treated by principal component analysis (PCA). All the individual analytes and their 2- and 3-component mixtures were fully discriminated by using a blend of 4 fluorophores. When necessary, the efficiency of discrimination was quantified as Mahalanobis distances. A UV-vis fingerprint method applied to the same synthetic mixtures was found to provide poorer discrimination.

In the subsequent studies we showed a possibility to discriminate beverages.

New prospects of determination of polyelectrolytes with nanostructures have been explored. The first approach is based on the formation of nanoparticles aggregates in the presence of the analyte, a cationic polyelectrolyte. This approach allowed solving the problem of determining low concentrations polyhexamethylene guanidine (PHMG), a cationic disinfectant. PHMG causes the aggregation of silver nanoparticles, which increases the intensity of Rayleigh scattering in solution. Another approach to the determination of charged polymers is based on the formation of mixed aggregates with magnetic and fluorescent nanoparticles. PHMG bound into such aggregates was separated from the excess of QDs with a magnet and determined by the intensity of fluorescence. The developed methodology for determining PGMG in waters feature wider linear ranges and lower detection limits than all known optical methods for determining PGMG.

One more approach is based on the aggregation of synthetic polyelectrolyte molecules by the analyte, which is observed by Rayleigh scattering spectroscopy. The method for the determination of antibiotic amikacin is based on its covalent binding to a pre-prepared reagent, a N-hyrdoxysuccinimidyl ether of an anionic polymer. The determination of amikacin is feasible without any separation step in the presence of large amounts of inorganic salts and nitrogen-containing compounds, as well as comparable amounts of protein. The fourth approach allows us to determine a bifunctional analyte (malondialdehyde, MDA) at mg/L level due to the formation of its triple covalent aggregates ("sandwiches") with the nanoparticles (silica) and a fluorophore (ethylenediamino-fluorescein) followed by separation of "sandwiches" from the excess of the fluorophore by centrifugation with subsequent fluorimetric determination of MDA. Determination of MDA is not interfered by comparable concentrations of sulfamethoxazole, sulfadiazine, piracetam and chloramphenicol; protein interferes.
