The purpose of the work: development based on planar electrodes/glass plates, modified with carbon nanodots and analytical reagents, electrochemical and optical sensor elements sensitive to microquantities of practically relevant analytes and their application for the analysis of real objects at the sampling site with analytical signal processing by pocket electronics . Research methods: voltammetry, potentiometry, transmission electron microscopy, energy dispersive X-ray spectroscopy. UV, visible, IR, 1H NMR spectroscopy, fluorescence analysis, thermometry, thermal analysis, preparative chemistry of methods of obtaining and functionalizing carbon nanodots, results of their research and methods of their immobilization on the surface of transducers. The results of research on the production of carbon nanodots (CDs) (by electrochemical oxidation of carbon / hydrothermal synthesis), functionalization (with carboxyl, carbonyl, hydroxyl, amino, and fluorine-containing groups) and research on CDs (morphology and physicochemical characteristics) and immobilization of CDs and reagents are given. on the surface of transducers (planar carbon electrodes).  Product Description popup.authors Alekseev Sergei A.
