Electrophoric/electrochemical devices involving two separate, parallel, flat surfaces consisting of metal/insulator nano-laminates. The use of two nano-laminates increases the electrophoretic flow through a channel of given dimensions at a given applied voltage as compared to prior approaches. The introduction of these separate electrodes to the walls of the fluid channel maximizes the amount of exposed metal and minimizes the diffusion distance to facilitate electrochemical redox reactions. The combination of rapid solvent turnover and efficient detection of low concentrations of analyte creates a fast and sensitive detector.
