Relevance. Improvement and development of new optical and electrochemical sensors and sensor systems for on-site and in vitro analysis of practically important objects is relevant from the point of view of metrological characteristics of the methods, expressivity and cost of a single determination. The goal is to develop sensitive elements of optical and electrochemical sensor systems based on carbon nanomaterials modified with transition metal oxides, supramolecular systems and organic reagents and their application for on-site and in vitro analysis of some natural, medical and biological objects and food products with improved metrological characteristics of the methods and the use, among other things, smartphones for recording the analytical signal, its processing and saving the analysis results. Tasks: to obtain functionalized carbon nanoparticles (CNPs) and nanodots (CDs), to study their morphology and physicochemical characteristics and to immobilize them and analytical reagents on the surface of transducers; to study the chemical-analytical characteristics of the obtained sensitive elements of optical and electrochemical sensors and to identify correlations between the nature of functional-analytical groups on their surface and the sensitivity, selectivity, and stability of the analytical signal of the optical/electrochemical sensor; to develop methods for determining the corresponding analytes (heavy metal ions, organic compounds, oxidants, solution pH, etc.) using the obtained sensors and to test them during the analysis of natural, food, medical and biological objects on-site and in-vitro with the involvement of pocket electronics. Ideas, Hypotheses. The employees of the department have developed unique methods for the synthesis of TMCs and CDs and a number of original one-stage approaches for creating sensitive elements of sensors.
