Guillaume HERLEM is professor of materials chemistry at the University of Franche-Comté (France). He graduated from Pierre and Marie Curie University and obtained his doctorate from the University of Franche-Comté in physico-chemistry. He is one of the founding members of the SINERGIES laboratory (https://lab-sinergies.f). Until now, he is working on: 1 – Chemistry and electrochemistry for Health. A) The electropolymerization of bifunctional aliphatic molecules either in a non-aqueous medium (amines, thiols, siloxanes) or in an aqueous medium (amino acids)-application to (bio)sensors. B) The amination of chemically inert (bio)materials by alkali metal alkylamides to produce overgrafting of macromolecules for therapeutic purposes has been applied to surgical prostheses made of fluoropolymers (expanded polytetrafluoroethylene or ePTFE). 2-Electrical energy storage. Highlights -discoveries of new (electro)chemical reactions: synthesis of alkylamides for the amination of materials and electropolymerization of bifunctional aliphatic monomers such as A-(CH2)n-B (n≥2) can be irreversibly electropolymerized on metals and semiconductor surfaces (e.g. linear polyethylenimine, polysulfide and polypeptide-like polymers). -Syntheses of nanovectors based on TRAIL cytokine (apoptosis-inducing ligand linked to TNF) targeting cancer cells. TRAIL is a protein involved in antitumor immune surveillance, inducing apoptosis without being toxic to healthy cells.
