摘要: A ferrocene functionalized SWCNT noncovalent nanohybrid was investigated by using a ferrocene/SWCNT interdigitated construction film as an electrode for l-glutamate detection. Ferrocene could immobilize on the surface of bundles, and hybrid had high stability not only in water but also organic solvent such ethanol acetone (no sediment observed more than 3 months). The be thoroughly dispersed adhere tightly onto glass substrates to form film. Owing existence carbon nanotubes, active electrochemical mediators, unique structure film, exhibited catalytic efficiency, sensitivity, fast response during detection low concentration (1 μM). good linear relationship between current obtained from 1 7 μM.
