Abstract
The synthesis of gold nanoparticles functionalized by gadolinium chelates constitutes an attractive way for combining imaging and therapy. The presence of gadolinium chelates allows monitoring their biodistribution after intravenous injection in small animals by magnetic resonance imaging (MRI) while the gold core strongly absorbs the X-ray photons. This feature is exploited for X-ray imaging but also for radiotherapy.

About the authors Christophe Alric obtained his Master degree in inorganic chemistry at the University of Lyon (France) and he is now a PhD student in the group of Prof. Olivier Tillement. His research activities are focused on the elaboration of gold nanoparticles combining medical imaging and therapeutic capacities.
Céline A. Mandon received the Doctorat de spécialité in Biochemistry (2005) from the Université Lyon 1. She was post-doctoral researcher (2005-2006) at the Laboratory of Oxidative Stress, Chaperons and Apoptosis in Lyon (CGMC—CNRS-UMR5534), where she developed bioluminescent and fluorescent stress inducible cell based assays. She is currently post-doc researcher at the laboratory Creatis-LRMN (CNRSUMR-5220), on the Animage platform, where she is in charge of cell labeling by hybrid nanoparticles, used as contrast agents for in vivo imaging.
Jacqueline Taleb received a diploma in pharmacy (1998) from the University of Algiers and a Master 2 Research in Biomedical engineering (2007) from the Université Lyon 1. The subject of the training was “X-ray radiosensibilizating effects of gold nanoparticules on healthy and tumoral cells”. She is currently PhD student at Creatis-LRMN (CNRS-UMR-5220), on the Animage platform, where she is developing a tumoral model and testing radiotherapeutic effects of radioactive nanoparticules and their detection by MR, optic and scientigraphic imaging.
