Summary:The article examines the electrokinetics in a straight microchannel with locally competitive contributions from ionic and electronic conductance due to the presence of an embedded bipolar electrode. Researchers observe the migration and concentration enrichment of the charged fluorescent dye BODIPY disulfonate to demonstrate the dynamics. They conclude that the dynamics can be used to generate extended field gradients for tailoring analyte focusing in a microchannel.
