2.8 μm paramagnetic beads in a 12 pl droplet were dispensed from a reservoir on a 33 μm electrode device with a 3 μm gasket. The bead solution was first dispensed into the reservoir with a pipette. The electrodes in the channel were turned on in sequences to pull the bead solution out from the reservoir (3) to (6). The reservoir electrode and the third channel electrode were then turned on to split the bead droplet in (7) and (8).
