Bubble jetting in acoustic microdroplet vaporization
Anunay Prasanna, Samuele Fiorini, Gazendra Shakya +1
Acoustic droplet vaporization denotes the phase-change of micron- and sub-micron-sized droplets upon the application of high-amplitude ultrasound. The asymmetric collapse of the in…
Cavitation by phase shift of focused shock waves inside a droplet
Samuele Fiorini, Guillaume T. Bokman, Anunay Prasanna +6
Localized cavitation in liquids and soft tissues, typically initiated by the rarefaction phase of high-amplitude ultrasound waves, is leveraged in several biomedical applications s…
Measurement of traveling pressure waves inside a droplet
Sayaka Ichihara, Samuele Fiorini, Yoshiyuki Tagawa +1
Shock wave-droplet interactions have been receiving increasing attention due to their relevance in aviation fuel combustion and minimally invasive medical treatments, yet quantifyi…
Translational dynamics of lipid-coated microbubbles driven by ultrasound
Marco Cattaneo, Outi Supponen
Ultrasound-driven microbubbles are increasingly being investigated for both molecular imaging and therapeutic applications. To be effective, these bubbles must be brought into clos…
Shock compression-based equation of state for perfluorohexane
Anunay Prasanna, Guillaume T. Bokman, Samuele Fiorini +4
Perfluorohexane is a biocompatible material that serves as a liquid core for acoustically-responsive agents in biomedical applications. Despite its relatively widespread usage, the…
Faraday Wave Singularities Trigger Microbubble Jetting
Marco Cattaneo, Louan Presse, Outi Supponen
Wall-attached bubbles can produce repeated jets under gentle ultrasound stimulation through the Faraday instability. We identify three distinct jetting regimes defined by the jetti…
Shape modes and jet formation on ultrasound-driven wall-attached bubbles
Marco Cattaneo, Louan Presse, Gazendra Shakya +6
Understanding how substrate-attached bubbles respond to ultrasound is important for applications from industrial cleaning to biomedical therapy. Under ultrasonic excitation, bubble…
Cyclic jetting enables microbubble-mediated drug delivery
Marco Cattaneo, Giulia Guerriero, Gazendra Shakya +4
The pursuit of targeted therapies capable of overcoming biological barriers, including the tenacious blood-brain barrier, has spurred the investigation into stimuli-responsive micr…
Positive pressure matters in acoustic droplet vaporization
Samuele Fiorini, Anunay Prasanna, Gazendra Shakya +2
Acoustically vaporizable droplets are phase-change agents that can improve the effectiveness of ultrasound-based therapies. In this study, we demonstrate that the compression part…
Synchrotron X-ray phase-contrast imaging of ultrasonic drop atomization
Anunay Prasanna, Luc Biasiori-Poulanges, Ya-Chi Yu +3
Ultrasonic atomization is employed to generate size-controllable droplets for a variety of applications. Here, we minimize the number of parameters dictating the process by studyin…
Shell viscosity estimation of lipid-coated microbubbles
Marco Cattaneo, Outi Supponen
Understanding the shell rheology of ultrasound contrast agent microbubbles is vital for anticipating their bioeffects in clinical practice. Past studies using sophisticated acousti…
Rebounds of deformed cavitation bubbles
Outi Supponen, Danail Obreschkow, Mohamed Farhat
Presented here are experiments clarifying how the deformation of cavitation bubbles affects their rebound. Rebound bubbles carry the remaining energy of a bubble following its init…
Luminescence from cavitation bubbles deformed in uniform pressure gradients
Outi Supponen, Danail Obreschkow, Philippe Kobel +1
Presented here are observations that demonstrate how the deformation of millimetric cavitation bubbles by a uniform pressure gradient quenches single collapse luminescence. Our inn…
Shock waves from non-spherical cavitation bubbles
Outi Supponen, Danail Obreschkow, Philippe Kobel +3
We present detailed observations of the shock waves emitted at the collapse of single cavitation bubbles using simultaneous time-resolved shadowgraphy and hydrophone pressure measu…
Scaling laws for jets of single cavitation bubbles
Outi Supponen, Danail Obreschkow, Marc Tinguely +3
Fast liquid jets, called micro-jets, are produced within cavitation bubbles experiencing an aspherical collapse. Here we review micro-jets of different origins, scales and appearan…
