Low-Temperature Chemical Synthesis of CoWO₄ Nanospheres for Sensitive Nonenzymatic Glucose Sensor

Herein, we report a novel and facile synthesis of CoWO₄ nanospheres for the nonenzymatic glucose sensor application. The detailed synthesis and material characterizations were reported. Interestingly, the glucose sensor performance of the CoWO₄ nanospheres exhibits a low detection limit as low as 0.7 μM with an ultrahigh sensitivity of 1416.2 μA mM^–1 cm^–2. The unique properties with the excellent electrochemical performance achieved by such facilely prepared CoWO₄ nanospheres render their prospective applications as low-cost and stable nonenzymatic glucose sensors.
