Multi-configuration 1D patterning of K562 cells using CSFIT-based acoustic tweezers. (a–d) Microscopy images of K562 cells taken by a CCD camera at the four excitation frequencies. Micro-objects are distributed in multiple 1D, parallel line-like patterns with different skew angles and interspacing. The pattern orientations agree with the orientations of SAW wave fronts in the simulation results (Fig. 3).
