Microbombs detonated by ultrasound can blast away tooth decay micro organism

Micro organism that trigger tooth decay may very well be blasted away by microscopic “bombs” detonated with an ultrasonic toothbrush.

Ultrasound may cause some liquids, corresponding to perfluorohexane (PFH), to quickly broaden and switch to gasoline. Some researchers have explored utilizing tiny degradable capsules containing these liquids to ship medicine contained in the physique or to blast away cancerous tumours.

Now, Xian-Zheng Zhang at Wuhan College in China and his colleagues have developed PFH-containing capsules designed to destroy biofilms – aggregations of microbes …
