We report the stepwise modification of Os-complex mediator (polyvinylimidazole-[Os(bipyridine)2Cl] (PVI-[Os(bpy)2Cl]) and glucose oxidase (GOD) within the inner nano-space of a carbon nanotube forest (CNTF) film. Owing to the controlled alignment of enzyme/mediator/ electrode in the ensemble, the prepared film electrode has both a high-efficiency (turnover rate of ca. 650 s-1) and a large net oxidation current (ca. 15 mA cm-2). The previous GOD electrodes developed by monolayer-based and polymer-based approaches have either of the performances (efficiency or net activity). In addition, the present GOD electrode is a flexible film that could be used by winding on needle devices.
