Abstract The NiCl(OH) nanosheet array grown in situ on the carbon cloth (NiCl(OH) NS/CC) was synthesized using only anhydrous ethanol and NiCl2·6H2O as a raw material in a mild hydrothermal method. In this paper, NiCl(OH) NS/CC was used as the working electrode for electrochemically sensing glucose under alkaline conditions. Compared with some reports of nickel-based electrochemical detection of glucose, the NiCl(OH) NS/CC electrochemical sensor demonstrates a high sensitivity of 8052.0 μA mM−1 cm−2, a wide linear range of 0.001–3.45 mM, a lower detection limit of 0.29 μM and a response time of less than 5 s. In addition, our sensors can effectively detect glucose in serum and saliva of human beings. Furthermore, the NiCl(OH) NS/CC catalyst has good long-term stability and is highly selective for glucose detection.

NiCl(OH) 纳米片阵列作为一种高灵敏度电化学传感器，用于检测人血清和唾液中的葡萄糖

摘要 以无水乙醇和NiCl2·6H2O为原料，采用温和的水热法合成了在碳布上原位生长的NiCl(OH)纳米片阵列(NiCl(OH) NS/CC)。在本文中，NiCl(OH) NS/CC 用作在碱性条件下电化学传感葡萄糖的工作电极。与一些基于镍的葡萄糖电化学检测报告相比，NiCl(OH) NS/CC 电化学传感器表现出 8052.0 μA mM-1 cm-2 的高灵敏度，0.001-3.45 mM 的宽线性范围，较低的检测限制为 0.29 μM，响应时间小于 5 秒。此外，我们的传感器可以有效检测人类血清和唾液中的葡萄糖。此外，NiCl(OH) NS/CC 催化剂具有良好的长期稳定性，对葡萄糖检测具有高度选择性。
