FIG. 3.

Demonstration of a continuous-flow sheathless electrokinetic separation of 5 μm and 15 μm-diameter spherical particles in a bifurcating microchannel: superimposed images (left in each panel) and predicted trajectories (right in each panel, blue and red lines are for 5 μm and 15 μm particles, respectively) at the entrance (a) and middle (b) of the main-branch, the bifurcation (c), the middle (d), and exit (e) of one side-branch. The inlet reservoir is at 800 V DC and the two outlet reservoirs are both grounded. The scale bars represent 100 μm.
