Abstract
Voltammetric sensors and sensor systems based on electrically conductive polymermodified electrodes are widely used to solve various analytical problems, such as detection of counterfeit medicines, beverages, technical fluids, etc. In this case, in general, sensors that are selective to one or another molecule of the analyte are used, which makes it impossible to recognize multicomponent mixtures containing various electroactive components, or multisensor systems from several electrodes must be used. The use of "smart" voltammetric sensors, the selectivity of which can be regulated in sity, allows to solve this problem quite simply. However, the voltammetric characteristics and properties of "smart" sensors have not been studied enough.
