N2 - Micro-band electrode was successfully fabricated by lamination method through sealing a piece of boron-doped diamond film inside a sandwich of two insulating plates, namely Teflon and silicon rubber as the gaskets. Characterization was performed using Raman and XPS spectra of the BDD film, while the fabricated micro-band was characterized by analyzing its SEM image. The electrode was examined for cyclic voltammetry of adenosine triphosphate solution, where an oxidation peak at +0.9 V vs. Ag/AgCl can be observed. The influence of scan rate and pH was also studied, in which pH 2 was selected as the optimum pH. The diffusion coefficient of 0.1 mM ATP at micro-band electrode was 3.84 x 10-8 m2/s, while the effective surface of the micro-band BDD electrode was 8.72 x 10-14 m2.
