Abstract |
The electron transfer of the glucose dehydrogenase (GDH) immobilized electrode which modified chitosan composites with mutiwalled carbon nanotubes (Chit-MWCNTs) was investigated through electrochemical method. MWCNTs were wrapped by Chit for dispersion in water soluble solution, and then Chi-MWCNTs adsorbed electrode was fabricated onto indium-tin oxide (ITO) electrode. And GDH enzyme for determination of glucose was loaded on the Chit-MWCNTs/ITO electrode. The GDH/Chit-MWCNTs/ITO electrode were dried without cross-linker. The electron transfer reaction of the GDH with electrode were observed using electrochemical techniques. Also, field emission scanning electron microscope (FE-SEM) was used for investigation of all electrode’s morphologies. The electrical signal of glucose was measured onto GDH/Chit-MWCNTs/ITO electrode by cyclic voltammetry (CV). The GDH/Chit-MWCNTs/ITO electrode shown that has a simple fabrication method, high sensitivity, low-cost, and fast electron transfer directly.
