Microstreaming velocity field distribution and geometric deformation of the cell membrane and microbubble in the bubble-fluid-cell system for a cell with relatively small elasticity of 1 kPa (A) or relatively large elasticity of 4 kPa (B); and the maximum microstreaming shear stress exerted on the cell membrane with various elastic modulus (C). The typical initial bubble radius is Rb0=1.5 μm, the US driving pressure amplitude is p=300 kPa, the US frequency is f=1MHz, and the initial distance between the bubble center and the cell membrane is set to be twice the initial bubble radius.
