Abstract
- The optrode integrated with light sources and electrical recording electrodes presents significant advantages. However, the performance of the optrode is still hindered by photoelectric artifact generated by optical stimulation. A controlled electrodeposition method of Pt-Black/PEDOT-GO (graphene oxide doped poly(3,4-ethylene-dioxythiophene)) double layer on gold microelectrode is developed for noise reduction in this work. The microscopic characterization shows that Pt-Black can increase the adhesion of PEDOT-GO to the substrate and prevent it from spreading around, thereby avoiding short circuits in adjacent microelectrodes. Moreover, the electrochemical measurements show that Pt-Black/PEDOT-GO can decrease impedance and improve electrochemical performance dramatically. Finally, the bench noise recordings show that Pt-Black/PEDOT-GO can simultaneously reduce background noise, photovoltaic noise and photoelectrochemical noise to less than $100~\mu \text{V}$.
