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...
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...
The project MetaHyp is one of the five projects labelled ANR in 2025 and led by CEISAM laboratory. With MetaHyp, Patrick Giraudeau aims to develop new ultra-sensitive NMR approaches for metabolomics, by developping new analytical approaches based on dynamic nuclear polarization, applied to the detection of biomarkers of clinical pathologies. Nuclear Magnetic Resonance (NMR) spectroscopy...
With her project SEEAFM, Estelle Lebègue, a lecturer-researcher at the CEISAM laboratory, has been selected as a laureate of the Emergence@INC 2026 call for projects. Through this scheme, CNRS Chemistry supports researchers—research fellows or associate professors recruited within the past 5 to 10 years—by funding innovative projects and encouraging scientific risk-taking. The SEEAFM project aims...
Morgane Vacher, CNRS research fellow at the CEISAM laboratory, is one of five winners of the 2025 Joséphine Awards presented by the Pays de la Loire Region. With the Joséphine Awards, the Pays de la Loire Region celebrates women with inspiring careers in a variety of fields (defence, research, artificial intelligence, sport and solidarity). The...
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...
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....
Clémence Queffelec, Senior Lecturer at Nantes University, at the Laboratory “Chemistry and Interdisciplinarity: Synthesis, Analysis, Modelling” (CEISAM), has been awarded the ARKEMA Prize by the French Academy of Sciences. The prize (€25,000), created in 2021, rewards decisive scientific advances in the development, characterisation, understanding or implementation of sustainable materials, i.e. materials whose life cycle and...
Pauline CRETIN (US2B; Molecular Engineering and Glycobiology Team) has defended her doctoral thesis entitled “Ecophysiology and importance of non-cyanobacterial marine diazotrophs (NCD)” on Friday, October 24, 2025. During her three years of doctoral research, Pauline studied diazotrophy using a model of non-cyanobacterial diazotrophic (NCD) bacteria. Monitoring of nitrogenase activity was carried out at the CEISAM...
From 3rd to 13th October, the 2025 Science Festival took place with the theme ‘Intelligence(s)’ and once again, the CEISAM laboratory was there! Yann Pellegrin, accompanied by other members of the laboratory, ran a chemistry stand at the Science Village, focusing on silly mistakes in chemistry. They also visited the paediatric ward at Nantes University...
