title: Electrochemical determination of reversible redox species at interdigitated array micro/nanoelectrodes using charge injection method.
abstract: In this work, the interdigitated array microelectrodes/nanoelectrodes (approximately 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 x 10(-7) M and 6 x 10(-9) M detection limits on the species concentration ar respectively achieved with the microelectrodes and the nanoelectrodes.
