在中性水溶液中制备了由电聚合吖啶黄素-黄素腺嘌呤二核苷酸（AF/FAD）膜修饰电极组成的混合膜。研究发现这些薄膜在玻碳、金和透明半导体氧化锡电极上稳定且具有电化学活性。杂化聚（吖啶黄）/FAD 薄膜显示出两个氧化还原对。采用电化学石英晶体微天平和循环伏安法研究杂化聚（吖啶黄）/FAD 薄膜的原位生长。采用聚吖啶黄/FAD杂化膜在水溶液中对二氢烟酰胺腺嘌呤二核苷酸（NADH）和烟酰胺腺嘌呤二核苷酸离子（NAD（+））进行电催化氧化和还原。聚（吖啶黄）/FAD 混合膜对 NADH 的电催化氧化和还原反应均具有活性。发现中性水溶液中聚(吖啶黄)/FAD杂化膜对L-胱氨酸、S4O62-、SO52-、S2O82-、NO2-和H2O2的电催化还原具有电催化还原活性。 (c) 2006 年电化学协会。
Hybrid films composed of electropolymerized acriflavine-flavin adenine dinucleotide (AF/FAD) film modified electrodes have been prepared in neutral aqueous solution. These films were found to be stable and electrochemically active on glassy carbon, gold, and transparent semiconductor tin oxide electrodes. The hybrid poly (acriflavine)/FAD film showed two redox couples. Electrochemical quartz crystal microbalance and cyclic voltammetry were used to study the in situ growth of hybrid poly (acriflavine)/FAD films. Electrocatalytic oxidation and reduction of dihydronicotinamide adenine dinucleotide (NADH) and nicotinamide adenine dinucleotide ion (NAD(+)) by a poly (acriflavine)/FAD hybrid film in aqueous solution were carried out. The poly (acriflavine)/FAD hybrid films were found active for both electrocatalytic oxidation as well as reduction reaction of NADH. The electrocatalytic reduction of L-cystine, S4O62-, SO52-, S2O82-, NO2-, and H2O2 by a poly (acriflavine)/FAD hybrid film in a neutral aqueous solution was found to be an electrocatalytic reduction activity.
