Renewal of the CEISAM NMR platform ISO 9001 certification
Following an evaluation process conducted by AFNOR, the CEISAM NMR platform ISO 9001 certification (initially obtained in 2022) was renewed for 3 years in November 2025 This certification marks a commitment towards a continuous improvement approach in the service of its users. It is a recognition of the involvement of the platform’s staff in a...
A highly reactive chemical intermediate stabilised by weak interactions
Researchers at the CEISAM laboratory (CNRS/University of Nantes) and the Interdisciplinary Centre for Nanosciences in Marseille (CINaM, CNRS/Aix-Marseille University) have succeeded in stabilising a highly reactive reaction intermediate using weak intramolecular interactions. Known as the Meisenheimer complex, this negatively charged and highly reactive intermediate has long been recognised by chemists in aromatic nucleophilic substitution reactions....

Our research teams
This Institute is organized into five research teams covering coherent areas of activity but which are based on different and highly complementary segments, giving rise to original transversal projects.
On the basis of fundamental and specific expertise, CEISAM is positioned in a certain number of niches of excellence at the interface with the fields of Health, Food chemistry and Materials, through privileged interactions at regional, national and international levels.
Platforms and equipment
To support our research activities, the CEISAM Institute owns many specialist equipments.
These instruments and equipment chains, sometimes intégrated into platforms, aim to synthesize, model, prepare and characterize organic or hybrid items. The European Union, the CNRS and the "Pays de la Loire" region have largely contributed to co-financing these platforms and equipments in particular in NMR, Mass Spectrometry, Molecular Modeling, Optical spectroscopies and microscopy.
