Department of Analytical and Structural Chemistry and Biology

Research team


The Department of Analytical and Structural Chemistry and Biology at ICSN has several research topics focused on analytical chemistry and structural biology. It relies on exceptional equipment and strong expertise in molecular modeling, structural crystallography, mass spectrometry, nuclear magnetic resonance (NMR), molecular / cellular biology and various purification / analysis methods.The projects carried out are based, for example, on the monitoring the distribution of compounds of interest in various tissues or biological materials, the study of complex mixtures, the structure determination of compounds extracted from plants or synthesis, the understanding of reaction mechanisms, the study of the 3D structure and dynamics of small molecules and biological macromolecules (alone or in interaction with partners or inhibitors) in the context of structural biology and drug design.This department belongs to the Institute of Chemistry of Natural Substances (ICSN) and has a long tradition of academic and industrial collaborations.
