Hydrothermal synthesis of NiWO4 crystals for high performance non-enzymatic glucose biosensors

Abstract

A facile hydrothermal route for the synthesis of ordered NiWO4 nanocrystals, which show promising applications as high performance non-enzymatic glucose sensor is reported. The NiWO4 -modified electrodes showed excellent sensitivity (269.6 μA mM-1 cm-2) and low detection limit (0.18 μM) for detection of glucose with desirable selectivity, stability, and tolerance to interference, rendering their prospective applications as cost-effective, enzyme-free glucose sensors.
