Peptides, Glycoconjugates and Metals in Biology

PGMB

Coordination: Dr. Laurence Grimaud

The team Peptides, Glycoconjugates and Metals in Biology is constituted of organic and inorganic chemists who share skills, and know-hows to synthesize and study the reactivity of bioactive molecules, bioconjugates and functional nanoparticles.
Combining organic synthesis, spectroscopies (IR, UV-Vis absorption, fluorescence, X-fluorescence) electrochemistry and biology, the research of the team is aimed at deciphering the reactivity and properties of bioinspired constructs ranging from the molecular to the supramolecular and colloidal scales. Applications include the fundamental understanding of the (bio)catalytic activity of metals complexes, the study of biomolecular interactions (membrane, peptides, proteins and glycoconjugates) and cellular imaging using tailored fluorescent, IR or X-fluorescent probes.
