Abstract

Top and bottom microelectrode glass slide sandwich es a channel made of adhesive tape and packed with reduced graphene oxide to make a new non-planar interdigitated microfluidic device. Novel device integration allows the packing of any transducer material at room temperature with no instrument. The electrical impedance spectroscopy signal is stable over long times, fits an equivalent circuit with well-defined circuit elements. Flow visualization concurs that electric double layer signal shifts to high frequency due to the disruption of the diffusive process from the increased convective flow. Charge transfer resistance appears at higher frequencies making the device rapid with high signal to noise ratio.
