Poster summary

In this work, a number of selectors containing a chiral blocks from a simple, accessible enantiopure compound of R- and S-alphamethylbenzylamine was synthesized. The chiral blocks were attached to fullerene (C60) through an intermediate adduct with dichloroacetic and malonic acids using the Bingel-Hirsch reaction, the structure of which was confirmed by NMR and IR spectroscopy. The sensitive layer of studied sensors consisted of layer-by-layer deposited graphene oxide and functionalized C60. The proposed sensors were characterized by cyclic voltammetry and electrochemical impedance spectroscopy. Morphological studies of sensors were carried out using scanning electron microscopy. Some patterns of changes in the electrochemical behavior of Lev depending on the composition of the sensitive layer of the sensor were obtained. Quantitative determination of Lev was carried out by differential pulse voltammetry. Moreover, the developed sensor can be used to detect Lev in real samples (biological fluids and tablet) with a good recovery percentage.
