| Research Abstract |
We aimed at distinguishing the responses from graphene basal plane and graphene edge when the graphene is used as an electrochemical electorde. Our idea is to use the interdigitated graphene electrodes with the same basal plane area but different edge lengths. We have designed such electrodes and developed the fabrication processes. We have observed the electrochemical signals assignable to the low dimensional structures from some of the electrodes. In parallel, we fabricated the interdigitated electrodes whose surface are fully covered by reduced graphene oxide. We have confirmed the difference in electrochemical responses depending on the redox species from the electrodes. The electrodes have been applied to the detection of cortisol, a stress marker.
