摘　　要：A method for fabrication of the ordered carbon nanotube (CNT) film, which was template-synthesized within the highly ordered pores of a commercially available alumina template membrane, modified glassy carbon (CNIT/GC) electrode was established. The CNT/GC electrode showed excellent electrocatalytic activity toward dopamine electrochemical reaction without introducing any electrochemically active group into CNT film or activating the electrode electrochemically. DA undergoes ideal reversible electrochemical reaction on CNT/GC electrode at low scan rate ( less than or equal to 20 mV/s) with an excellent reproducibility and stability. The CNT/GC electrode might be used in biosensors because the highly ordered CNT may present a steric effect on more efficient redox reactions of biomolecules.A method for fabrication of the ordered carbon nanotube (CNT) film, which was template-synthesized within the highly ordered pores of a commercially available alumina template membrane, modified glassy carbon (CNIT/GC) electrode was established.
