France-Japan Laboratoire International Associé (LIA) on “Chiral Nanostructures for Photonic Applications” (CNPA) - Hierarchical chiral nanostructures based on molecular assemblies for light management, sensor, chiral separation and catalysis has been created in 2015. The goal is to promote the collaborations between the partner laboratories (9 French groups, 7 Japanese groups) but also to give an official framework for French/Japanese exchange, especially for setting up the double/joint degrees for visiting researchers.
