Novel porous CoO nanosheets (NSs) were synthesized on the flexible carbon cloth (CC) substrate by a facile hydrothermal method and applied to construct a non-enzymatic sensor for glucose detection. The sensor is based on the electro-catalytic oxidation of glucose on the surface of CoO NSs. Since this particular nanostructure can provide large surface area and more active sites, the CoO NSs non-enzymatic sensor exhibits excellent analytical performance, such as a high sensitivity (8506 μA mM cm), a fast response time (less than 6 s), low detection limit of 1 μM, good selectivity, and long-term stability. The results suggest that the porous CoO NSs have great potential applications in the development of sensors for enzyme-free detection of glucose.
新型多孔 CoO 纳米片（NSs）通过简便的水热法在柔性碳布（CC）基底上合成，并应用于构建用于葡萄糖检测的非酶传感器。该传感器基于 CoO NSs 表面上葡萄糖的电催化氧化。由于这种特殊的纳米结构可以提供更大的表面积和更多的活性位点，因此 CoO NSs 非酶传感器表现出优异的分析性能，例如高灵敏度（8506 μA mM cm）、快速的响应时间（小于 6 s）、低检测限 1 μM、良好的选择性和长期稳定性。结果表明，多孔 CoO NSs 在开发用于无酶检测葡萄糖的传感器方面具有巨大的应用潜力。
