f1: The synthesis route for NiWO4 material and its application as high-performance non-enzymatic glucose sensors.

Mentions: We report herein, the preparation of octahedron-like nickel tungstate (NiWO4) crystals by using a facile hydrothermal method and their performances as enzyme-free glucose sensors, as illustrated in Fig. 1. To the best of our knowledge, this is the first report on application of NiWO4 microcrystals for non-enzymatic glucose sensors. It is found that the NiWO4-modified glassy carbon electrodes (GCE) exhibit good electrocatalytic activity toward the oxidation of glucose. Moreover, the biosensors so fabricated show superior analytical parameters, such as wide linear range, excellent sensitivity, and lower detection limit, desirable for electrochemical detection of glucose.
