Acoustically active antibubbles can potentially be used for ultrasound-guided drug delivery. In this presentation, we derive the oscillating behaviour of acoustic antibubbles with a negligible outer shell, resulting in a Rayleigh-Plesset equation of antibubble dynamics. Furthermore, we compare the theoretical behaviour of antibubbles to that of regular gas bubbles. We conclude that antibubbles and regular bubbles are acoustically active in a very similar way, if the liquid core is less than half the antibubble radius. For larger cores, antibubbles demonstrate highly harmonic behaviour, which would make them suitable vehicles in ultrasonic imaging and ultrasound-guided drug delivery.
