The institute of Chemistry and Biology of Membranes and Nano-objects (CBMN) is a joint research unit of the CNRS (main INC, secondary INSB), the University of Bordeaux and the Institut National Polytechnique de Bordeaux. The CBMN institute is also associated with Bordeaux Science Agro. CBMN has about 200 people (50% permanent and 50% non-permanent). It is a multidisciplinary institute and operates at the interface between ChemistryBiology and Physical by hosting 16 research groups gathered in four thematic poles: Chemical biology and Supramolecular chemistry (CBSC), Biomedical research, Fundamental and translational (BioFAP)Multiscale Biophysics (MSB)Nutraceutical, medical and food applications of biomolecules (NMFAB).

The European Institute of Chemistry and Biology (IECB) is an incubator for international research teams at the chemistry-biology interface, placed under the joint supervision of the CNRS, theInserm and University of Bordeaux.
Its mission is to bring together the most promising European chemists and biologists in a multidisciplinary environment, in order to develop high-level research programs in collaboration with public and private research centres. About fifteen research teams certified by an International Scientific Council, i.e. nearly 180 researchers, technicians and students, work on the site every day.
Their expertises revolve around 4 axis of research: bio-organic chemistry and chemobiology, molecular biophysics, structural biology, molecular and cellular biology.
