Analyzing and imaging living systems

The detection/analysis of an individual element in a complex dynamic mixture presents an actual challenge to link properties of a biological system to its chemical components. The complementary expertise of the teams drives the development of new biosensors relying on ultra-sensitive plasmonic particles,[i] nanoformulated EPR probes[ii] to image redox-active species in animals, persistent luminescent nanoprobes[iii] for tumor imaging or DNP to follow specific metabolites in biological media.[iv] Additionally, non-specific methods like chemical-nose sensors arrays[v] or unsupervised metabolomics[vi] combined with machine learning will establish new diagnostic technics.
