Cells entering in the sample stream are only deflected into the collection stream if they are labelled with a dielectrophoretically responsive label (i.e., beads). The DEP particles entering the collection channel after being focused into the center of the stream. The arrows indicate the direction of fluid flow. The electrode region of the microchannels comprise of sample and buffer inlets, as well as waste and collection outlets. Reprinted with permission from Hu et al., Proc. Natl. Acad. Sci. U. S.
