Abstract:Screen-printed carbon electrodes (SPCEs), modified with graphene oxide and poly(3,4ethylenedioxythiophene):polystyrenesulfonic acid (GO-PEDOT:PSS/SPCEs), and SPCEs modified with partially reduced GO and PEDOT:PSS (prGO-PEDOT:PSS/SPCEs) were studied for electrochemical transduction. Randles-Sevcik analysis showed that the prGO-PEDOT:PSS/SPCE has a higher effective surface area of 219.3 µm 2 in comparison to the unreduced GO-PEDOT:PSS/SPCE (87.0 µm 2) and the bare SPCE (71.7 µm 2). Using electrical impedance spe… Show more
