利用微技术制备的多壁碳纳米管在金电极上生长，作为定向和稳定固定镍铁氢化酶的平台。对该体系进行了微观表征和电化学表征。测量了H-2氧化电催化产生的高密度电流，在连续操作条件下稳定一个多月。这种纳米结构的氢化酶电极的功能特性适合氢生物传感和生物燃料的应用。
Multiwalled carbon nanotubes grown on gold electrodes manufactured by microtechnology techniques have been used as a platform for oriented and stable immobilization of a Ni-Fe hydrogenase. Microscopic and electrochemical characterization of the system are presented. High-density currents due to H-2 oxidation electrocatalysis, stable for over a month under continuous operational conditions, were measured. The functional properties of this nanostructured hydrogenase electrode are suitable for hydrogen biosensing and biofuel applications.
