Electrocatalytic oxidation of NADH at electrogenerated NAD+ oxidation product immobilized onto multiwalled carbon nanotubes/ionic liquid nanocomposite: application to ethanol biosensing.

本文报道了一种基于多壁碳纳米管/N-丁基-N-甲基吡咯烷鎓双(三氟甲磺酰)亚胺离子液体（MWCNTs/[C4mpyr][NTf2]）修饰玻璃碳电极的电化学生物传感器。通过电位循环将NAD+氧化产物（Ox-P(NAD+)）固定在MWCNTs/IL纳米复合层表面，形成稳定的氧化还原活性介体。该修饰电极可在0.05 V（vs. Ag/Ag...
