The Centre de Nanosciences et de Nanotechnologies (C2N) is a joint research unit from CNRS, Université Paris-Saclay and Université Paris Cité. It was founded on the 1st June 2016 from the merging of two former laboratories, leaders in their field : the Laboratoire de Photonique et de Nanostructures (LPN - CNRS) and the Institut d’Electronique Fondamentale (IEF - CNRS/Université Paris-Sud). In 2018, the teams moved together in a new building at the heart of Campus Paris-Saclay, in the south of Paris. The C2N is a flagship laboratory for research in nanoscience and nanotechnology in France, and in the world. It hosts the largest academic micro-nano-technology facility in France belonging to the national nanofabrication network Renatech. The research unit counts more than 400 membres, and is developing research in the field of material science, nanophotonics, nanoelectronics, nanobiotechnologies and microsystems, as well as in nanotechnologies. In all these fields, its research activites cover all the range from fondamental to applied science.
