Electrochemistry communications, 2014•ElsevierA direct electron transfer biofuel cell consisting of a pair of single walled carbon nanotubes
and enzymes on a single plane is reported, which allows for extremely close spacing of
electrodes. The discrete device has a measured power and current density of 18 mW/cm 2

Abstract
A direct electron transfer biofuel cell consisting of a pair of single walled carbon nanotubes and enzymes on a single plane is reported, which allows for extremely close spacing of electrodes. The discrete device has a measured power and current density of 18 mW/cm2 and 90 mA/cm2, respectively, into 200 TΩ. Analysis of measurements from up to 3 million devices in parallel shows that the performance will improve by at least 2 orders of magnitude at peak power.
