(a) The binary mixture (1.97 and 4.84 μm in diameter polystyrene beads) separation images from superimposing 1 min consecutive images of the moving beads at a high bead sorting rate −0.778 beads/s. (b) The separation images at a lower bead sorting rate −0.485 beads/s under the same experimental conditions. (c) The MOSFET drain current of the upper sensing channel containing mostly 4.84 μm polystyrene beads (with one 1.97 μm bead). (d) The MOSFET drain current of the lower sensing channel containing mostly 1.97 μm polystyrene beads (with one 4.84 μm bead).
