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.
