A propos : CBMN & IECB

The institute of Chemistry and Biology of Membranes and Nano-objects (CBMN) is an institute belonging to CNRS, University of Bordeaux and to the Bordeaux Polytechnic Institute. It is multi-disciplinary and operates at the interface between Chemistry, Biology and Physics by hosting 14 research laboratories distributed in three departments: Biomimetic and Therapeutic Chemistry, Biophysical Chemistry and Biology and Biotechnology. 8 Technical Platforms (NMR, X-Rays, Electron Microscopy, Mass spectrometry, Vibrational spectroscopy (IR-Raman-BA-PWR), Molecular Modelling, AFM, and peptide synthesis.) nicely complement the high level expertise of research laboratories. CBMN is part a national plan called “Invest to the Future”: IDEX Bordeaux, Labex AMADEUS, VIBNANO and LISA Carnot Institute. A close partnership is particularly developed with pharmaceutical and formulation industries and also with industries in the nutrition and health domains (lipids and vine/wine products).

The European Institute for Chemistry & Biology (IECB), UMS 3033, is an incubator of international and interdisciplinary research teams at the interface between chemistry and biology. The platform of structural  biophysical chemistry gathers several equipments and expertises available at IECB to answer structural and functionnal questions on molecules of medical interest, with particular emphasis on topics related to biomembranes, supramolecular chemistry and gene transfer.
