An amperometric glutamate biosensor based on immobilization of glutamate oxidase onto carboxylated multiwalled carbon nanotubes/gold nanoparticles/chitosan composite film modified Au electrode.

本文报道一种新型安培法谷氨酸生物传感器，将谷氨酸氧化酶（GluOx）共价固定于羧基化多壁碳纳米管（cMWCNT）、金纳米颗粒（AuNPs）和壳聚糖（CHIT）复合膜修饰的金电极上。复合膜通过循环伏安电沉积构建，cMWCNT经EDC/NHS活化后与GluOx表面氨基形成酰胺键。采用SEM、FTIR、EIS和CV对电极进行表征。传感器在...
