Emergent behavior in particle-laden microfluidic systems informs strategies for improving cell and particle separations by Vahey, Michael D., Voldman, Joel

“…These investigations reveal the mechanisms underlying the dynamic patterns formed by micron-scale particles as they impinge on a dielectrophoretic force barrier: their tendency to aggregate and recirculate under constant operating conditions, and to reorganize when the operating conditions are changed. …”
