Ultrasound & Water Blast Contamination from Surfaces
Soaps, disinfectants, powerful chemicals and high-pressure sprays are the standard when it comes to removing tough gunk like mascara, grease, blood and bacterial biofilms. There now appears to be a better way to scrub contaminants off surfaces–a gentle stream of water pulsing with ultrasonic soundwaves.
For several years, researchers at the University of Southampton in the UK have been working on a device they call the StarStream, which has a special nozzle that injects bubbles and ultrasound into a water stream.
In a number of videos, ultrasonics and underwater acoustics professor Timothy Leighton demonstrates the water-gun-shaped device’s ability to scrub away mascara between a metal file’s teeth, tissue from bone, grease from a spring and bacteria from teeth. In their most recent study, they say StarStream is good enough to disinfect medical instruments after contamination with tissue, body fluids and bacteria. Learn more below.
