Abstract

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