Figure 3.

Snapshot images illustrating the continuous electrical sorting of 5 μm-diameter spherical particles and 3.5 μm-diameter/6 μm-length peanut-shaped particles in an asymmetric double-spiral microchannel by C-iDEP: (a) inlet, (b) center, and (c) trifurcation of the channel. The average DC electric field across the channel length is around 250 V/cm. Note that the peanut-shaped particles have been individually highlighted in (a) and (c) for a better illustration. The block arrows indicate the flow directions.
