| 摘 要： | 将纳米氧化锌与血红蛋白(Hb)的混合液,通过肌醇六磷酸酯(IP6)层层自组装于玻碳电极(GCE)表面,制备了{Hb-ZnO/IP6}6修饰电极.用循环伏安法、电化学阻抗光谱和场发射扫描电镜对{Hb-ZnO/IP6}6膜进行了表征.实验结果表明:{Hb-ZnO/IP6}6/GCE呈现层状三维多孔结构,实现了血红蛋白和电极表面的直接电子转移.该修饰电极对过氧化氢有很好的电催化活性,线性范围为2.00×10-6～1.12×10-4mol.L-1,最低检测限为1.40×10-6mol.L-1(信噪比S/N=3),米氏常数为5.1 mmol.L-1.

| Abstract: | Inositol hexakisphosphate(IP6) and the mixed solution of zinc oxide nanoparticles and hemoglobin(Hb) were alternately modified onto the surface of a glassy carbon electrode(GCE)through layer-by-layer self-assembly technique for constructing {Hb-ZnO/IP6}6/GCE.{Hb-ZnO/IP6}6/GCE was characterized with cyclic voltammetry(CV),electrochemical impedance spectroscopy(EIS) and field emission scanning electron microscopy(FESEM).Experimental results showed that the {Hb-ZnO/IP6}6/GCE exhibited three-dimensional porous ... |
