'Raman barcodes' distinguish 20 SARS-CoV-2 variants by their RNA architecture

A research team led by distinguished professor Giuseppe Pezzotti at the Biomedical Engineering Center, Kansai Medical University (Japan), has demonstrated that differences in the molecular structures of viral RNA can be captured as "Raman barcodes," enabling the identification of 20 SARS-CoV-2 variants and subvariants. These findings are expected to contribute to the development of a rapid method for identifying newly emerging viral variants.
