将硫化钼(MoSx)-氢氧化镍（Ni(OH)2）按顺序电沉积在柔性碳纳米管/聚酰亚胺（CNT/PI）复合膜上，构建了无酶葡萄糖传感器。采用扫描电镜（SEM）、透射电镜（TEM）、x射线粉末衍射（XRD）和x射线光电子能谱（XPS）对传感材料进行了表征。采用循环伏安法和安培法考察了所制备的纳米材料对葡萄糖氧化的电催化活性。Ni(OH)2/MoSx/CNT/PI传感器具有10 ~ 1600 μM葡萄糖的宽线性范围、快速响应（<3 s）、低检测限（5.4 μM）、良好的选择性、良好的重复性和长期稳定性（2周）等优良性能。Ni(OH)2和MoSx之间具有明显的协同效应。此外，该传感器成功地应用于标准加样法检测人血清样品中的葡萄糖，回收率满意。
A nonenzymatic glucose sensor was constructed by electrodepositing molybdenum sulfide (MoSx)-nickel (II) hydroxide (Ni(OH)2) in sequence on a flexible carbon nanotube/polyimide (CNT/PI) composite membrane. The sensing material was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray powder diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The electrocatalytic activity of the as-prepared nanomaterial toward glucose oxidation was investigated by cyclic voltammetry and amperometric measurement. The Ni(OH)2/MoSx/CNT/PI sensor demonstrated excellent properties including a wide linear range from 10 to 1600 μM of glucose, rapid response (<3 s), low detection limit of 5.4 μM, good selectivity, good repeatability, and long-term stability (2 weeks). The superior performances were attributed to the pronounced synergistic effect between Ni(OH)2and MoSx. Furthermore, the excellent sensor was successfully applied to detect glucose in human blood serum samples by standard addition method with satisfactory recovery.
