Vibrating nanodroplets may invade a tumor

Sending tiny droplets to a tumor and having them vaporized using focused ultrasound: It could be a new way of tracing a tumor or deliver drugs locally. Researchers of the University of Twente now demonstrate a new phenomenon triggering droplet vaporization: It happens at the exact acoustic resonance frequency and causes fast and efficient lowering of the pressure inside the droplet, until below the threshold value for vaporization. The research results are published in Physical Review Letters.
