The discovery surprised the researchers because it contradicts classical physics theories, as the wavelength of ultrasound is much longer than the size of the virus. In theory, this difference in size would prevent interaction.
"The phenomenon is entirely geometric. Spherical particles, such as many enveloped viruses, absorb ultrasound wave energy more effectively. It's that accumulation of energy inside the particle that causes changes in the structure of the viral envelope until it ruptures. Therefore, if viruses were triangular or square, they wouldn't undergo the same 'popcorn effect' of acoustic resonance," Bruno explains.
He also points out that since the process depends strictly on the shape of the viral particle and not on genetic mutations, variants such as those observed during the pandemic (omicron and delta, for example) do not affect the effectiveness of the technique.
That's cool as hell.
Hopefully this pans out into a workable treatment (which will probably be years from now, but I'll take what I can get at this point).
