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). |
