Construction of glutamate biosensor based on covalent immobilization of glutamate oxidase on polypyrrole nanoparticles/polyaniline modified gold electrode.

本文报道了一种用于检测谷氨酸的高灵敏电化学生物传感器。该传感器将谷氨酸氧化酶（GluOx）通过戊二醛共价固定于电沉积在金电极（Au）表面的聚吡咯纳米粒子/聚苯胺（PPyNPs/PANI）复合膜上。采用循环伏安法、扫描电镜、X射线衍射、透射电镜、傅里叶变换红外光谱和电化学阻抗谱对酶电极进行表征。传感器在pH 7.5的0.1 M磷酸钠缓...
