Cu-S/Ni碗状复合阵列用于无酶葡萄糖传感器

Cu-S/Ni Bowl Composite Array for Enzyme-free Glucose Sensor

采用两步电沉积法成功制备了Cu-S/Ni层状纳米碗状阵列。过渡金属硫化物具有低成本、高活性、导电性能好、资源丰富等优点,是非酶促葡萄糖传感器的理想选择。电化学测试结果表明,Cu-S/Ni电极具有1378.068μA·mM;cm;的高灵敏度,0.5~4mM的线性范围较宽,0.0184uM的低检测极限。这些结果表明,Cu-S/Ni层状碗状纳米结构可作为无酶葡萄糖传感器的发展方向。

Cu-S/Ni layered nanobowl arrays were successfully prepared by two-step electrodeposition.Transition metal sulfide has the advantages of low cost, high activity, good conductivity and abundant resources, so it is an ideal choice for non-enzymatic glucose sensor. The electrochemical test results show that the Cu-S/Ni electrode has A high sensitivity of 1378.068 μA· mm-1 cm-2, A wide linear range of 0.5 ~4 mM, and A low detection limit of 0.0184 u M. These results indicate that Cu-S/Ni layered bowl nanostructures can be used as the development direction of enzyme-free glucose sensors.
