(A) SSAW-based 3D particle focusing observed from different perspectives (I: top view, II: side view). (B) Top-view bright field images and (C) side-view fluorescent stacking images of the particle flow pattern without (OFF) and with (ON) SSAW focusing. The dashed lines in (C) indicate the channel boundaries. (D) Top-view images showing cell focusing by SSAW. Please refer to Supplementary Video 1.
