Jean-Charles ARNAULT
(CEA Research Director, Diamond Sensors Laboratory)
Jean-Charles Arnault is a Research Director at CEA (French Atomic Energy Commission). He obtained his PhD in 1993. From 1993 to 2007, he was assistant professor at Strasbourg University. In 2007, he joined the Diamond Sensors Laboratory at CEA. His expertise concerns diamond nucleation and growth, interactions between Microwave Plasma CVD with surfaces using in situ surface analysis methods and electron microscopies. Since 2008, his research activities have focused on surface modifications of diamond nanoparticles using plasma or thermal treatments to control their surface terminations and confer new surface properties. As an illustration, plasma hydrogenated nanodiamonds exhibit a very high stability in aqueous solutions and could be used for bio-applications. These cationic hydrogenated nanodiamonds are currently used for siRNA delivery in Ewing sarcoma cells. Moreover, they constitute also active nanoparticles inducing the in-vitro radiosensitisation of human cancer cells under irradiation. Very recently, an efficient radioactive labelling of detonation nanodiamonds was reported by his group using a tritium micro-wave plasma.
He has published more than 100 papers in international peer-reviewed scientific journals and he has given 30 invited talks in international conferences and in foreign universities. He wrote three book chapters dealing with diamond nanoparticles and diamond nucleation. He is currently one of the editors of Diamond and Related Materials.
