N2 - Modification of gold electrode using single-walled carbon nanotubes (SWCNTs) has been done. The synthesis of SWCNTs on the gold electrode surfaces was carried out using chemical vapor deposition (CVD) method. The performance of the electrodes as a sensor was characterized using dopamine (DA) solution at pH 4 by cyclic voltammetry. A change in electrode capacitance was found before and after DA detection. The detection limit and sensitivity of the electrodes are 0.79 μM and 3.414 μA mm−2 μM−1, respectively. No interference signal was found from ascorbic acid (AA) during DA measurement.
