DA concentration was determined using the cyclic voltammetry and square-wave (SW) stripping voltammetry methods. The results show that the nano-structured electrodes exhibit a more ten times higher limit of detection then non-structured BDDE and strongly dependence of morphology i-NCD. Electrochemical oxidation of DA was carried out at BDDE, with which very stable and reproducible was observed within 4 h. The analytical detection limit nanostructured BDDE of anodic dopamine maximum (3xstandard deviation/slope) was determined to be SW: 1.7x10-6 M, adj. R square=0.998, and the maximum was shifted to 0.55 V vs. Ag/AgCl at the optimum conditions.
