Figure 4

Dynamic control of particle separation in viscoelastic DLD via flow rate at (a) Wi = 0.1, (b) Wi = 0.5, and (c) Wi = 0.9. (a) Particles with diameter 8 μm and 12 μm behave zigzag mode at low Wi, i.e., low flow rate; (b) 12-μm particles enter displacement mode while 8-μm particles remain unchanged when the flow rate gradually increases; (c) Both 12-μm and 8-μm particles finally enter displacement mode over a critical flow rate. In this way, D c can be tuned by flow rate in viscoelastic DLD. The images are superposed over the Supplementary Video S3.
