were shown to successfully report the reduction of ferricyanide and detect the impact of Pt nanoparticles on a microelectrode. Another type of remote reporting was recently demonstrated using a conventional three-electrode system, with the working and reference electrodes in the detection cell separated from the counter electrode in the reporting cell with a glass frit. The advantage of this cell design over the traditional closed-bipolar system was that the three-electrode cell allowed for direct thermodynamic control over the electrochemistry of interest. Electrochemical signals of nanoamps were successfully reported through fluorescence induced by the passage of current at the counter electrode. However, this system still required different fluorogenic reactions depending on whether oxidation or reduction was performed in the detection cell. The reduction of p-benzoquinone in the presence of HPTS in the reporting cell was used to report oxidation of ferrocenedimethanol in the detection cell, whilst the oxidation of AR to resorufin in the reporting cell was used to report on the reduction of hexaammineruthenium(III) in the detection cell.
