Amination of Multiwalled Carbon Nanotubes and Investigation of its Efficiency in Glucose Oxidase Immobilization

The synthesis of amine functionalized carbon nanostructures (multiwalled carbon nanotubes) wasinvestigated. The synthesized nanostructure was characterized with FT-IR, and XRD methods. The results demonstrateda unique nanostructure with no destruction of the nanostructure shape. In addition, the presence of amine groups on thenanostructure surface was confirmed by FT-IR and XRD methods. This nanostructure was used for one-stepimmobilization of glucose oxidase (GOx). The result of cyclic voltammetry showed a pair of well-defined and quasireversiblepeaks for direct electron transfer of GOx in the absence of glucose.
