本文将3D纳米结构花状CoS电沉积在石墨烯胶带电极（GTE）上,制备了一种对葡萄糖响应良好的电化学传感器。结构分析显示电沉积的CoS均匀地分散在了电极上。实验结果表明,制备的花状CoS/GTE葡萄糖传感器在0.025 ~ 1.0 mmol·L^-1显示出良好的线性关系,灵敏度为323.3 μA·(mmol·L ^-1)^-1·cm^-2,检出限为8.5 μmol·L ^-1 (S/N = 3),而且制备的传感器能够应用于血清葡萄糖的检测。这表明本文制备的传感器具有一定的应用潜力。

Three-dimensional (3D) nanostructural Flower-like cobalt sulfide (CoS) on flexible self-supporting graphene tape electrode (GTE) with remarkably electrocatalytic activity toward glucose was successfully prepared by electrodeposition. Structural characterizations revealed that the electrodeposited CoS was highly dispersed on GTE as an active material. The fabricated binder-free and self-standing CoS/GTE shows a good linear response in the range of 0.025 ~ 1.0 mmol·L^-1, reaching a high glucose sensitivity value of 323.3 μA·(mmol·L ^-1)^-1·cm^-2 and a low detection limit of 8.5 μmol·L ^-1 (S/N = 3). Moreover, the as-prepared sensor was well applied for glucose determination in human serum. Thus, the self-supporting, binder-free, low-cost sensor has good potential as a promising device for practical quantitative analysis of glucose in human serum.
