Delphine Muriaux and Cyril Favard’s team, in collaboration with the Institut XLIM (CNRS/Université de Limoges), the Photonique numérique & nanosciences laboratory (LP2N, CNRS/Institut d’optique graduate school/Université de Bordeaux) and CEMIPAI (CNRS/Université de Montpellier), have developed an ultrasensitive, non-invasive and fast optical method capable of detecting, identifying and measuring the size and concentration of nanoplastic and nanometal particles, as well as infectious viruses such as HIV or SARS-CoV-2, without any a priori knowledge of the sample contents. The system is compact and virtually insensitive to external sources of noise, such as stray light and vibration, enabling it to be used directly in a microbiological safety cabinet.
