Photosensitization worsens the formation of atmospheric ultrafine particles

These key results to which scientists from the IRCELYON laboratory have contributed (CARE team), are the subject of a publication by the INC (CNRS Institute for Chemistry) in its letter “En direct des labos” intended for the media:
