FIG. 8.

The stable limit cycle trajectories of (a) HL60 leukemia cells and (b) polystyrene beads of d = 10 and $20\hspace{0.17em}\mu$m diameter at Re = 151 inside the L₃ cavity. We display the limit cycle orbit of multiple cells in a cell population. Considering that the diameter of entrapped HL60 cells is $d\ge 25\hspace{0.17em}\mu$m, the limit cycle orbits form closer to the vortex core.
