在酸性水溶液中制备了电聚合鲁米诺-黄素腺嘌呤二核苷酸（FAD）复合膜修饰电极。这些膜是稳定的和电化学活性的，并且可以在玻璃碳、铂、金和透明半导体氧化锡电极上产生。杂化聚（鲁米诺）/FAD膜显示两个氧化还原对。采用电化学石英晶体微天平和循环伏安法研究了聚鲁米诺/FAD杂化膜和聚鲁米诺杂化膜的原位生长。将修饰电极转移到不同的酸性水溶液中，观察到两个氧化还原对和杂化膜的形式电位是pH依赖性的。研究了在不同pH值的水溶液中，聚鲁米诺/FAD杂化膜对NADH和NAD（+）的电催化氧化和还原。结果表明，该杂化膜对NADH的电催化氧化和NADH/NAD（+）的可逆电催化反应具有良好的活性。(c)2006 Elsevier B.

Hybrid films composed of electropolymerized luminol-flavin adenine dinucleotide (FAD) adsorbed film modified electrodes have been prepared in aqueous acidic solutions. These films are stable and electrochemically active, and can be produced on glassy carbon, platinum, gold, and transparent semiconductor tin oxide electrodes. The hybrid poly(luminol)/FAD film showed two redox couples. Electrochemical quartz crystal microbalance and cyclic voltammetry were used to study the in situ growth of hybrid poly(luminol)/FAD and poly(luminol) films. The modified electrode was transferred into various aqueous acidic solutions, the two redox couples and the formal potentials of the hybrid films were observed to be pH-dependent. The electrocatalytic oxidation and reduction of NADH and NAD(+) by a polyluminol/FAD hybrid film in aqueous solutions with various pH were carried out. The electrocatalytic oxidation of NADH and the reversible electrocatalytic reactions of NADH/NAD(+) using a poly(luminol)/FAD hybrid film were found to be active. (c) 2006 Elsevier B.V.
