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

A team of chemists and microbiologists at Michigan State University has found that an all-optical method can be used to detect natural vibrational frequencies made by individual viruses as a way to identify them. In their study published in Proceedings of the National Academy of Sciences, the group found a way to bounce light off viruses and detect the resulting patterns of vibrations, which could be easily identified.
