Enantioselective Voltammetric Sensors: New Solutions

Аннотация

A review of new approaches and solutions in the development and application of enantioselective voltammetric sensors for the recognition of optical isomers of biologically active compounds and medicines is presented. The main methods of electrode modification by enantioselective selectors are discussed, i.e., the application of inclusion complexes, molecularly imprinted polymers, elements of living systems and their analogs, inorganic and organic materials with the effect of chirality, and also supramolecular structures. The main analytical characteristics of some sensors and sensor systems of the electronic tongue type for the recognition and determination of enantiomers in various samples are presented. Methods of processing of voltammetric data for the elimination of the effect the memory of measurements and the cleanup of analytical signals at low concentrations of enantiomers are considered.
