a Inertial and b stable cavitation doses for nanodroplet mediated (ND) sonothrombolysis with different peak negative pressures compared with a control group of phosphate buffered saline (PBS) with ultrasound. The ultrasound excitation parameters were 700kHz, 10ms pulse length, and 20 cycles. * indicates p < 0.05 compared with the control group (N = 3)
