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…
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…
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…
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…
