Abstract: | Prussian blue (PB) nanoparticles were immobilized onto gold electrodes using L-cysteine, 1,3-propanedithiol, and 1,8-octanedithiol as a bridge between the gold surface and the PB nanoparticles by the self-assembly method. The obtained PB/thiol/Au electrodes exhibit direct and indirect electrocatalytic activity toward DL-homocysteine (HCys) oxidation. It is possible for these PB nanoparticles modified electrodes to be used for the determination of HCys. The text was submitted by the authors in English. |
