At low acoustic amplitudes micron-sized antibubbles are more stable and predictable than their bubble counterparts. This is probably owing to the endoskeleton content of an antibubble. It was also found that only a single pulse of ultrasound at a higher, but still clinically safe, amplitude was enough to cause an antibubble to rupture. This indicates that at lower acoustic amplitudes antibubbles can be carefully controlled and used in diagnostics, and at higher acoustic amplitudes they can be made to rupture and release their therapeutic contents.
