Abstract

A poly(3,4-ethylene-dioxythiophene) (PEDOT) electrode was prepared by electropolymerization of 3,4-ethylene-dioxythiophene (EDOT) in the presence of sodium dodecyl sulfate (SDS). The electrode was combined with centri-voltammetry for the first time and applied for dopamine (DA) detection. Under the experimental conditions, SDS provides a high density of negative charges to the PEDOT electrode and by this way the electrode attracts the positively charged DA. Also by applying centrifugation, effective accumulation of DA onto the electrode surface was achieved. Two linear ranges 1 × 10^-9 M to 1 × 10^-5 M and 2 × 10^-5 M to 1 × 10^-1 M with two LOD values of 5.9 nM and 3.1 nM were found for the developed system. Sample application and interference study were also conducted.
