Neww research suggests that coronavirus may be vulnerable to ultrasound vibrations, within the specific frequencies.

The team, with the help of computer simulations, modelled the virus’ mechanical response to vibrations.

It did so across a range of ultrasound frequencies and found that vibrations between 25 and 100 megahertz triggered the virus’ shell and spikes to collapse. Moreover, it starts to rupture within a fraction of a millisecond.

This effect takes place in simulations of the virus in air and water. The researcher is Tomasz Wierzbicki from the Massachusetts Institute of Technology.

The very spike-like proteins feed onto healthy cells. They subsequently trigger the invasion of viral RNA.

The study was published in the Journal of the Mechanics and Physics of Solids. The team introduced acoustic vibrations into the simulations. Besides, they observed how the vibrations rippled through the virus structure across a range of ultrasound frequencies.
