    Abstract

    In this contribution a SU8/glass-based microfluidic sensor is described with two closely spaced parallel electrodes for highly selective measurements using the redox cycling (RC) effect. Using this sensor, a RC amplification of ~2000x is measured using the ferrocyanide redox couple, which is much higher than the 400x reported so far [1]. Moreover, an analytical expression is derived that predicts the amplification factor based on the sensor geometry.
