多孔氧化铜纳米片无酶传感葡萄糖Porous Copper Oxide Nanoflakes Non-Enzymatic Sensor Glucose

摘要:

本文采用液固反应与高温退火相结合的方法,在不使用有机试剂及稳定剂的条件下在铜基体上成功的合成了三维交错多孔氧化铜纳米片。氧化铜的三维多孔结构,使其具有大的比表面积并且纳米片上的介孔和微孔有利于电子的传递。利用壳聚糖良好的生物兼容性,导电性和成膜性制备壳聚糖氧化铜有机–无机复合材料电极用于葡萄糖的无酶电化学检测。此电极具有制备简单、响应快速检测线低的优点,并且在常见干扰物尿酸,抗坏血酸,多巴胺等共存条件下对葡萄糖检测具有良好的选择性。

In this paper, three-dimensional porous copper oxide nanoflakes were successfully synthesized on the copper substrate without the use of organic reagents and stabilizers by the combination of liq-uid-solid reaction and high-temperature annealing. The three-dimensional porous structure of copper oxide has a large specific surface area, and the mesopores and micropores on the nanosheets are conducive to the transmission of electron. Using good biocompatibility, conductivity and film of chitosan are used to prepare chitosan copper oxide organic-inorganic composite electrode for nonenzymatic glucose electrochemical sensor. This electrode has the advantages of simple preparation, fast response and low detection line and the sensor is almost insensitive to common interference, such as dopamine, uric acid and ascorbic acid.
