The use of colloidal particles ~e.g., microbeads! in a microfluidic system is of central importance for many emerging bioanalytical and biotechnological applications. With the advent of microfluidics,1–3 many of these bead-based platforms are being implemented in a lab-on-a-chip format.4 This letter
characterizes the behavior of beads in microfluidic systems, and reports the dynamic formation of patterns of beads in a steady-state recirculation flow.
