以甲基苯胺蓝(P017-TB)共价修饰的甲基丙烯酸酯为骨架，合成了一种pH相关的双电子转移氧化还原聚合物。从嗜热菌分离的纤维二糖脱氢酶(FAD-MtCDH)的黄素脱氢酶结构域(FAD-MtCDH)在P017-TB中被包埋在P017-TB中是低电位生物阳极的基础，其开路电位为−240 mV对Ag/AgCl.最大电流密度为60μACM−2at−150 mV。与胆红素氧化酶生物电极相结合，得到了开路电压为720 mV、功率密度为6.1wcm/μ的生物燃料电池。
A pH-dependent, two-electron transfer redox polymer was synthesized based on a methacrylate backbone with tunable properties covalently modified with toluidine blue (P017-TB). Entrapment of the isolated flavodehydrogenase domain of cellobiose dehydrogenase from Myriococcum thermophilum (FAD-MtCDH) within P017-TB is the basis for low-potential bioanode with an open circuit potential of −240mV vs. Ag/AgCl and a maximum current density of 60μAcm−2at −150mV. Together with a bilirubin oxidase biocathode a biofuel cell with an open circuit voltage of 720mV and a power density of 6.1μWcm−2was obtained.
