In this paper, glucose oxidase (GOx) was covalently immobilized on the single-walled carbon nanotubes (SWNTs) via carbodiimide bond by forming amide linkages between the residual amine of GOx and carboxylic acid groups on the SWNTs tips. The functionalized SWNTs were successfully immobilized on the surface of a glassy carbon (GC) electrode. The modified electrode with SWNTs and SWNTs-GOx showed excellent quantitative response of reduction current for the determination of H2O2 and glucose, respectively.
Keywords:Single-Walled Carbon Nanotubes, Glucose Biosensor, Electrochemistry
