Abstract

Dopamine detection is investigated by using annealed platinum membrane on Ti/n-Si substrate for the first time. Oxidation/reduction peaks with and without dopamine in pH7 solution measured by cyclic-voltammetry (CV) are observed clearly. The sensor shows repeatable and stable CV curves. The oxidation/reduction peak currents increase with increasing scan rate. The peak current increases with increasing pH value. Dopamine with a low concentration of 1 μM and small sample volume of 10 μL is detected in current-time measurement within the short time of 5 s.
