Particles with a diameter of ∼0.5 µm in a dilute (volume fractions φ∞ < 4 × 10−3) suspension assemble into highly elongated structures called “bands” under certain conditions in combined Poiseuille and electroosmotic flows in opposite directions through microchannels at particle‐based Reynolds nu...
