A new way to construct small electrodes by the use of metal micro-beads is described. Gold beads of 1.5 to 3.0 mm diameter were used to construct inexpensive and disposable microelectrodes with overall structural diameters of £ 6 mm and electrode diameters of £ 5 mm. The voltammetric response of these electrodes is consistent with existing theory and the electrodes exhibited the sigmoidal waves expected at ultramicroelectrodes.
