Abstract
A new breed of microelectrode sensor arrays for oxidation-reduction potential (ORP) measurements in situ at environmental sites has been successfully developed. The microelectrodes were fabricated from glass using a two-step, HF-based meniscus etching process, and demonstrated electrochemical performance nearly identical to that of the commercial millielectrode, with significantly faster response times.
