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.
