BioSonics spectroscopy can 'listen' to the sounds made by individual viruses

Summary

Nutrition label

90% Informative

Chemists and microbiologists at Michigan State University found that an all-optical method can be used to detect natural vibrational frequencies made by individual viruses as a way to identify them.

The sound was too faint to hear with the human ear, but too high, at a frequency 1 million times higher than humans can hear.
