摘　　要：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323.3μA·(mmol·L^(-1))^(-1)·cm^(-2),检出限为8.5μmol·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(Co S)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 Co S was highly dispersed on GTE as an active material.The fabricated binder-free and self-standing Co S/GTE shows a good linear response in the range of 0.025~1.0 mmol·L^(-1),reaching a high glucose sensitivity value of 323.3μA·(mmol·L^(-1))^(-1)·cm^(-2)and a low detection limit of 8.5μmol·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.
