Nonenzymatic Glucose Sensor Based on Porous Co(3)O(4) Nanoneedles

Herein, porous Co(3)O(4) nanoneedle arrays were synthesized on nickel (Ni) foam (Co(3)O(4) NNs/NF) by one-step hydrothermal method. Some electrochemical methods were used to investigate its nonenzymatic glucose sensing performance in alkaline solution. The results show that the sensitivity of Co(3)O...

description Herein, porous Co(3)O(4) nanoneedle arrays were synthesized on nickel (Ni) foam (Co(3)O(4) NNs/NF) by one-step hydrothermal method. Some electrochemical methods were used to investigate its nonenzymatic glucose sensing performance in alkaline solution. The results show that the sensitivity of Co(3)O(4) NNs/NF electrode to glucose is 4570 μA mM(−1) cm(−2). The linear range is 1 μM-0.337 mM, and the detection limit is 0.91 μM (S/N = 3). It also displays good selectivity and repeatability for glucose. The good electrochemical sensing performance of Co(3)O(4) NNs/NF based sensor for glucose can be attributed to interconnected porous structure and large specific surface area of Co(3)O(4).
