The comparison of the destruction degree of samples under different treatment conditions. a is the control group. From left to right, only 1 mL saline is incubated for 1.2.3 min, respectively. B is the sinusoidal ultrasound group. From left to right, 1 mL saline is incubated for 3 min and the intensity of sinusoidal ultrasound is 0.5, 1 and 1.5 W/cm2, respectively. c is the pulse ultrasound group. From left to right, 1 ml saline is incubated for 3 min and the intensity of pulse ultrasound is 0.5, 1 and 1.5 W/cm2, respectively.
