Abstract

The study proposed simple methods with hydrothermal method and physical vapor deposition coating technique (sputter coater) to prepare Pt nanoparticles attach on ZnO nanorods, and then applied in non-enzymatic glucose sensor. Glucose sensing is tested using electrochemical measurement, including cyclic voltammetry and amperometry method. In cyclic voltammetry measurement, the sensitivity of ZnO and Pt/ZnO NRs sensor are 5.0273 and 32.0527 μA/cm2-mM when an applied potential at 0.1 V, which is carried out different glucose concentration from 0 mM to 8 mM. For observing the stability and selectivity, we were used the amperometry method to measure various glucose concentration and interfering species (ascorbic acid and uric acid). It is demonstrated that the Pt/ZnO NRs sensor exhibited excellent stability and anti-interference performance.
