ERC SUMMIT – Site-specific Ultrasensitive Magnetic resonance of Mixtures for Isotopic Tracking

Exploring the potential of fast and hyperpolarized nuclear magnetic resonance methods for “omics” sciences, this project is led by Patrick Giraudeau and the MIMM research team relies on cutting-edge equipments from the CEISAM NMR platform.

The SUMMIT team is developing new tools based on nuclear magnetic resonance (NMR) to obtain information on complex biological questions in the areas of life, environmental, food and forensic sciences.

NMR is a cutting-edge technique that provides crucial information on molecules in biological samples at the atomic level. For instance, NMR can help finding new biomarkers of a certain pathology, or provide information on the authenticity of a food sample. In this context, SUMMIT is developing more sensitive and resolutive methods, that will be applied to a variety of biological questions.


In more details

Metabolomics, fluxomics and isotopomics show great promises towards tracking the origin of biomarkers in complex biological environments, in the areas of life, environmental, food and forensic sciences. NMR spectroscopy is a major cutting-edge analytical tool for such “omics” sciences thanks to its high quantitative and structure elucidation potential, and to its ability to access site-specific isotope content. 13C NMR plays a central role, but numerous applications are currently out of reach of 13C NMR due to its low sensitivity.

The SUMMIT team is developing a groundbreaking analytical workflow relying on two of the most powerful NMR methods: dissolution dynamic nuclear polarization and ultrafast 2D NMR. This approach will allow the simultaneous measurement of 13C fingerprints from multiple low-concentrated biomarkers molecules in complex mixtures, which is impossible with existing methods. The high potential of this analytical strategy will be demonstrated on a variety of relevant biological studies, through applications in metabolomics, fluxomics and isotopomics.
