In this work, the interdigitated array microelectrodes/nanoelectrodes (∼0.2 mm2 surface area) have been fabricated and characterized using the charge injection method for the electrochemical determination of reversible redox species. Using p-aminophenol as the redox species, approximately 4×10-7 M and 6×10-9 M detection limits on the species concentration are respectively achieved with the microelectrodes and the nanoelectrodes.
