摘要: Dielectrophoresis (DEP) is the motion of particles under influence a nonuniform electric field. In insulator-based dielectrophoresis (iDEP), required fields are generated with insulating structures embedded in microchannel. These distort field distribution when an potential applied. This contribution presents experimental characterization electrokinetic (EK) and DEP velocities set target particles, DC potentials, additional innocuous used as fillers. Streak-based particle velocimetry tapered channel was to assess motion. Filler various sizes were added at different volume fractions (ϕ) suspending media containing particles/cells. The presence filler resulted distortions dissimilar behaviors caused by particle–particle interactions. mutual interactions exploited improve enrichm...
