Characterization and Electrochemical Response of Sonogel Carbon Electrode Modified with Nanostructured TiO2 and ZrO2 Film to Detect Common Neurotransmitters

Abstract

A new modified carbon electrode was developed by coating with nanostructured titanium dioxide and zirconium dioxide film and mixed film on top of graphite carbon electrode to detect common neurotransmitters such as 3,4-Dihydroxy-L-phenyl-alanine (L-DOPA) and dopamine. Cyclic Voltammetry (CV) was the method for the detection with these new sonogel modified electrodes, which showed good reversibility and reproducibility. This study proved that the mixture of TiO2 and ZrO2 is promising and could be expanded due to their good thermal stability, good conductivity and chemical inertness.
