Working mechanism for deforming a cell by acoustic streaming. a) Simulation and b) experimental results for acoustic streaming flow patterns around an oscillating bubble; c) acoustic streaming patterns around the oscillating bubble in the presence of a particle positioned at (50 μm, −50 μm) relative to the bubble center; d) an enlarged picture of panel (c) showing the nonuniform flow field near the cell and the shear force on the cell. The color indicates the magnitude of the streaming velocity from min (blue) to max (red), while the arrows indicate the direction of the streaming velocity.
