Improved Performance for the Electrochemical Sensing of Acyclovir by Using the rGO-TiO₂-Au Nanocomposite-Modified Electrode.

ABSTRACT: An electrochemical sensor for sensitive sensing of acyclovir (ACV) was designed by using the reduced graphene oxide-TiO₂-Au nanocomposite-modified glassy carbon electrode (rGO-TiO₂-Au/GCE). Transmission electron microscopy, X-ray diffractometer, and X-ray photoelectron spectroscopy were used to confirm morphology, structure, and composition properties of the rGO-TiO₂-Au nanocomposites. Cyclic voltammetry and linear sweep voltammetry were used to demonstrate the analytical performance of the rGO-TiO₂-Au/GCE for ACV. As a result, rGO-TiO₂-Au/GCE exerted the best response for the oxidation of ACV under the pH of 6.0 PB solution, accumulation time of 80 s at open-circuit, and modifier amount of 7 µl. The oxidation peak currents of ACV incr
