Rising Stars SEEMI Project 2026-2027

Estelle Lebègue will receive funding from Region Pays de la Loire for her SEEMI (Single-Entity Electrochemistry coupled to Microscopy Imaging) project thanks to the Rising Stars program, which aims to serve as a springboard to strengthen applications for European applications (ERC). In line with her theme of single-entity electrochemistry, Estelle would like to combine this...

New equipment for CHEM-Symbiose plateform !

CHEM-Symbiose platform is dedicated to the synthesis of small molecules. Since 2013, CHEM-Symbiose has been developing its expertise for its partners through its two activities: custom synthesis and/or research collaboration. Located at the CEISAM laboratory (UMR6230) at Nantes University, CHEM-Symbiose is certified by IBiSA, Biogenouest, and CNRS. Through its chemical library, CHEM-Symbiose is also a...

ChemAI ANR project led by François-Xavier Felpin

The project ChemAI is one of the five projects labelled ANR in 2025 and led by CEISAM laboratory. With ChemAI, François-Xavier Felpin aims to make AI-assisted chemical reaction optimization fully accessible to synthetic and process chemists by developing methods that are faster and more efficient with less experimental data. Chemistry, particularly synthetic chemistry, is undergoing...

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.
