We successfully fabricated microgap monolayer graphene electrodes (MMGEs), which is a pair of electrodes in which the basal planes of two monolayer graphenes are arranged in parallel facing each other across a small gap of 20 μm, without using a microfabrication process. We measured the redox cycling in the MMGE using (ferrocenylmethyl) trimethylammonium bromide and observed an excellent redox cycling under low-speed scanning conditions of 0.005 V/s. The collection efficiency reached 97% and it was almost independent of the scan rate.
