Abstract
⺠The dynamic oscillations of a 10-μm-diameter bubble insonated at 70 kHz were modeled. ⺠Poincaré maps and bifurcation diagram show that bubble oscillations bifurcate at a MI = 0.32. ⺠Experimental ultrasonic release of drug from micelles occurs at a MI = 0.37. ⺠The onset of release correlates with the intensity of the subharmonic. ⺠This correlation hints at insonation conditions that could facilitate drug delivery.
