Abstract A facile hydrothermal route for the synthesis of ordered NiWO 4 nanocrystals, which show promising applications as high performance non-enzymatic glucose sensor is reported. The -modified electrodes showed excellent sensitivity (269.6 μA mM −1 cm −2 ) and low detection limit (0.18 μM) with desirable selectivity, stability tolerance to interference, rendering their prospective cost-effective, enzyme-free sensors.
