The aim of this research was to determine the biodistribution and the labeling of radio nanoparticle with 64CuCl2, the nanoparticles Cu(acac)2/F-TiO2 were mixed with 64CuCl2 (20-37 MBq), then the final solution was used to injected healthy Wistar rats to probe the absorption of nanoparticle inside tissue trough of the groups OH that are formed during the functionalization of the Cu(acac)2/F-TiO2. The “in vivo” evaluation after realize the images study in micro PET equipment, uptake of the radio-nanoparticle was observed in the digestive system in the healthy Wistar rats.展开更多
