Abstract

A graphene-zinc oxide (ZnO/GR) nanocomposite film was fabricated on the glassy carbon electrode (ZnO/GR/GCE), and used for the measurement of tyrosine (Tyr) by differential pulse voltammetry (DPV). It was found that the ZnO/GR nanocomposites can improve the peak currents of tyrosine significantly due to the synergetic effect. The oxidation peak current was linearly related to tyrosine concentration in the range from 1.0 μM to 800.0 μM. The detection limit was calculated to be 0.5 μM (S/N = 3). Finally, the introduced electrode was successfully used for quantifying tyrosine in real samples. © 2017 The Authors.
