Towards photochemistry on a sub-molecular scale

08 March 2024
A team at the IPCMS has succeeded in controlling an elementary photochemical reaction on a sub-nanometric scale, by concentrating light in a nanometric volume at the top of a metal tip.

The article recently published in Nature Nanotechnology (Doi : 10.1038/s41565-024-01622-4): Submolecular-scale control of phototautomerization / Anna Roslawska, Katharina Kaiser, Michelangelo Romeo, Eloïse Devaux, Fabrice Scheurer, Stéphane Berciaud, Tomas Neuman and Guillaume Schull, is the subject of a news item on the CNRS Physique website.
