FIELD: chemistry.
SUBSTANCE: invention relates to a method of preparing carbon-containing indicator electrodes modified with nanoparticles of Au, Pt, Pd, Ni, Cu. Modification is carried out by depositing metal nanoparticles obtained by laser ablation of metal targets in clean solvents in the absence of stabilisers onto the working surface of the indicator electrode and holding (for not less than 5 minutes) the working surface in a respective dispersion (with concentration of not less than 0.05 g/l), followed by drying on air at room temperature.
EFFECT: method is simple, reactant-clean, and is not complicated by the need to use high temperatures and toxic organic substances.
