Electrochemical determination ofdopamine and ascorbic acidusing a 3-D Nanoporous Gold Thin Film |
| 초록 |
We fabricated athree dimensional nanoporous gold thin film(NPGF) onto a Au substrate using asimply and rapidelectrochemical deposition method. The NPGF electrode analysis by scanning electron microscope and reveals the formation of nanopores, approximately 30nm in diameter and 150nm thick.DPV(differential pulse voltammetry)was measured for the determination ofdopamine in the varying concentration(0.1μM~40μM) using a NPGF in the presence of ascorbic acid. DPV measurements of mixture of dopamine, ascorbic acid and uric acid.The high sensitivity feature of NPGF is expected that apply for real sample biosensor application.
