Covalently linked layers of glucose oxidase, single-wall carbon nanotubes and poly-L-lysine on pyrolytic graphite resulted in a stable biofuel cell anode featuring direct electron transfer from the enzyme. Catalytic response observed upon addition of glucose was due to electrochemical oxidation of FADH(2) under aerobic conditions. The electrode potential depended on glucose concentration. This system has essential attributes of an anode in a mediator-free biocatalytic fuel cell.
葡萄糖氧化酶、单壁碳纳米管和聚-L-赖氨酸在热解石墨上的共价连接层形成了一个稳定的生物燃料电池阳极，其具有酶的直接电子转移特性。添加葡萄糖后观察到的催化反应是由于在有氧条件下FADH(2)的电化学氧化。电极电位取决于葡萄糖浓度。该系统具有无介质生物催化燃料电池中阳极的基本特性。
