摘要
本文采用多孔聚碳酸酯(PC)模板在加热条件下通过溶液渗透和共沉淀制得了Al/Ni双氢氧化物纳米线,并将其修饰到玻碳电极制成无酶葡萄糖传感器。考察了该传感器在不同扫描速度时的循环伏安行为,比较了裸玻碳电极、不同修饰电极对响应电流的影响。在优化条件下进行葡萄糖检测,线性范围为2.0×10-5~1.3×10-3 mol/L,检出限可以达到5.0×10-6 mol/L。该方法快捷、灵敏、分析性能好,操作简便。可将其应用于血清中葡萄糖含量的测定。
Al/Ni double hydroxide nanowires were fabricated through solution infiltration and coprecipitation in heating conditions using poly carbonate membrane (PC) templates. The glassy carbon electrode was modified with A;/Ni double hydroxide nanowires to construct nonenzymatic glucose sensor. The cyclic voltammetry behavior of this sensor at different scanning rate and the influence of different modifications electrode on the response current were investigated. The resulting sensor offered an excellent amperometric response for glucose in the range of 2.0×10^-5~1.3×10^-3mol/L with a detection limit of 5× 10^-6 mol/L at the optimized conditions. This method is fast,sensitive, simple, and was applied for the determination of glucose in serum with satisfactory results.
