| סיכום: | Title screen The electrochemical behaviour of cysteine (Cys) at a graphite electrode modified with gold nanoparticles (G-Aunano electrode) was studied by cyclic voltammetry. It was found that the graphite electrode-Au nanoparticles show an electrocatalytic activity towards the oxidation of Cys in 0.1 M NaOH. At 0.05 V, there is an “inverse” maximum in the cathodic voltammogram of Cys. Using a G-Aunano electrode, the dependence of the peak current of the “inverse” maximum on Cys concentration was linear in the range from 1 to 14 pM, and the detection limit was 0.6 pM. The proposed analytical method is simple, rapid and sensitive. Режим доступа: по договору с организацией-держателем ресурса |
