The boron-doped diamond electrode with carrier density of 5.5×10¹⁹/cm³ showed high electrochemical response to methylene blue in aqueous solution. The cathodic and anodic current peaks due to leuco-methylene blue / methylene blue redox system were observed clearly on the diamond electrode in the solution containing methylene blue with lower concentration than 10 μM. It was also possible to detect methylene blue in the coexistence of another dye, brilliant blue FCF by using diamond electrode.
