This work describes the electrochemical method of boron-doped diamond (BDD) modification by poly-melamine to obtain organic film. The detection of adenine, guanine and caffeine were carried out by differential pulse wave voltammetry. The poly-melamine modified B-NCD electrodes exhibit excellent activity towards the electrochemical oxidation of all examined analytes. The poly-melamine modified BDD electrodes in all measurements exhibit a larger peak current and are more sensitive compared to the unmodified BDD electrodes. The detection limit for the adenine, guanine and caffeine for modified BDD electrodes by poly-melamine was found with the range of 0.4-0.2 µM, 0.02 nM and 0.4 µM respectively.
