High Current Density Wired Quinoprotein Glucose Dehydrogenase Electrode

摘要

Glucose electrodes were prepared by 'wiring' quinoprotein glucose dehydrogenase,GDH (EC 1.1.99.17) to glassy carbon with an osmium complex containing redox-conducting epoxy network. Their current density at 70 mM glucose concentration reached 1.8 mA/sq cm when 15 micrograms /sqcm of the enzyme having an activity of
