Abstrakt: Electrode sites of a photolithographically fabricated microelectrode array have been demonstrated to function as surface-enhanced Raman Spectroscopy (SERS) microelectrodes. The 5 × 15 μm iridium electrodes on the substrate are electroplated with silver and activated by standard procedures. Working and counter-electrode functions are integrated onto the same assembly. The electrode is shown to yield adenosine and pyridine spectra at low concentrations and submilliwatt laser power.
