Out-of-plane streaming vortices are generated via the oscillating glass slide. (a) Out-of-plane rotation of a HeLa cell is demonstrated at ~85 kHz and 30 VPP, respectively. (b) Numerical simulation of the vibration mode of the glass slide at 86,937 Hz yields parallel displacement lines. (c) Simulated streaming profile reveals two vortices inside the PDMS microchannel that is positioned along the parallel displacement lines on the glass slide. (d) 1 μm fluorescent beads are used to visualize the experimental streaming profile inside the microchannel at ~85 kHz and 30 VPP.
