Ascorbic acid (AA) and dopamine (DA) play a significant role in the function of the central nervous, renal and hormonal systems. The deficiency or incompatibility of their levels may lead to the symptoms of many diseases such as cancer, Parkinson's disease and cardiovascular disease. Because of their electrochemical activity, AA and DA detection is always attracting the intense interest in electroanalysis.Unfortunately, AA is always coexisting with DA in organisms, sharing a similar oxidation potential in electrochemical detection. To overcome this problem, various carbon based materials including carbon nanotubes, carbon nanofibers and graphene have been combined with conducting polymers, metals or metal oxides. In this study, we reported that fabrication of poly(3,4-ethylenedioxythiophene) /electrochemically reduced graphene oxide (PEDOT/ERGO) nanocomposites on Au electrode. The characterization of PEDOT/ERGO/Au electrode was performed by XPS, EDS, and SEM techniques. Synthesized PEDOT/ERGO/Au nanocomposite electrode was used as an electrocatalysts for dopamine biosensor application. PEDOT/ERGO/Au electrode was exhibited to the higher catalytic effect compared to naked Au, PEDOT-modified Au, and ERGO-modified Au electrodes.
