Con esa lectura lograron identificar 20 variantes y subvariantes.","fuente":"phys","fuenteNombre":"Phys.org","color":"#2b5c8a","autor":"","url":"https://phys.org/news/2026-10-raman-barcodes-distinguish-sars-cov.html","imagen":"https://scx1.b-cdn.net/csz/news/tmb/2026/raman-genome-for-sars.jpg","tema":"ciencia","subtemas":["variantes del coronavirus","espectroscopia raman","diagnóstico molecular","vigilancia epidemiológica","arn viral"],"entidades":["Giuseppe Pezzotti","Kansai Medical University","Japón"],"formato":"dato","entretenimiento":false,"pubTs":"2026-10-20T17:40:27.000Z","indexTs":"2026-10-20T17:41:58.047Z","hash":"17b00da393900372a6c9831604ee102ebced8e435ba2ce1a99466b729fcc8f97","tsa":{"time":"Oct 20 17:42:23 2026 GMT","provider":"freetsa.org","sobre":"sello"},"stats":{"views":0,"likes":0,"clicks":0,"dwell":0},"tipo":"normal","registro":"hallazgo","porQueImporta":"Cada variante del virus tiene una huella propia que se puede leer con un láser y un análisis de la luz que rebota en la muestra, sin necesidad de procesos largos. Si el método se vuelve rápido y accesible, un laboratorio podría detectar en pocas horas una variante nueva que empiece a circular, algo clave para decidir a tiempo qué medidas tomar. El límite es que el trabajo todavía está en etapa de demostración, y falta probarlo en muestras reales y en hospitales antes de usarse en la práctica.","quienFirma":"Kansai Medical University (Japón)","confianza":"revisado","consulta":null},"sello":{"hash":"17b00da393900372a6c9831604ee102ebced8e435ba2ce1a99466b729fcc8f97","sello":"ee122f11ce0c364a45b1727e796842c7d01cd796c07631d2ff23b39be6364224","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6569570,"aleatorio":"1607ded9f1a8e4a20807c153bef6d89d8bbb2eb0b2b277246c5daa36cefe20bb","tiempo":"2026-10-20T17:42:00.000Z"},"nist":{"cadena":2,"pulso":1991990,"salida":"76F0DE7F9A820C7A89556F1478EB869AF84162CB8313ECAC1481D673E26A980003474CE5336597FC416C60971C0F431200EC56629D4FF0177DAB6FC78F830F0B","tiempo":"2026-10-20T17:41:00.000Z"},"noAntes":"2026-10-20T17:42:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 20 17:42:23 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"'Raman barcodes' distinguish 20 SARS-CoV-2 variants by their RNA architecture","descripcion":"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.
