因此，构建和发展非贵金属纳米阵列结构对葡萄糖的灵敏和选择性检测具有重要意义。本论文以对苯二甲酸和钴离子为原料，在泡沫镍表面水热合成了Co-MOF纳米片阵列。在碱性介质中，Co-MOF/NF对葡萄糖氧化具有很强的电催化活性。作为一种很有前途的无酶传感器，在Co-MOF/NF中获得了< 5s的快速安培响应、10，886 μ A mM（-1）cm（-2）的高灵敏度和1.3nM的低检测限（信噪比= 3）。研究表明，该材料具有长期稳定性和良好的重现性，可用于人血清和果汁中葡萄糖的检测。
It is important to construct and develop non-noble-metal nanoarray architecture for sensitive and selective detection of glucose. In this paper, we testify the hydrothermal synthesis of Co-MOF nanosheet array on nickel foam from aqueous Co2+ and terephthalic acid. The resulting Co-MOF array on Ni foam (Co-MOF/NF) exhibits strong activity for glucose oxidation electrocatalysis in alkaline media. As a promising enzymatic-free sensing, the speedy amperometric response of < 5s, high sensitivity of 10,886 mu A mM(-1) cm(-2) and low detection limit of 1.3 nM (signal/noise = 3) are obtained in the Co-MOF/NF. Our study shows that the material possesses longtime stability and great reproducibility and may be used for the glucose detection in human blood serum and fruit juice.
