The use of radioactive nanoparticles as imaging and therapeutic agents is increasing globally. Indeed, the use of these nanoparticles as perfect theranostic agent is highly anticipated in the pharmaceutical market. Among the radioactive nanoparticles, liposomes, solid lipid nanoparticles and polymeric nanoparticles are the most studied. However little information among adverse reactions, absorbed dose and correct dose to achieve the theranostic goal in a translational application is available. We developed a radioactive polymeric nanoparticle and calculated the absorbed dose in animal model (Wistar rats) using the OLINDA/EXM program. The results showed that some nanoparticle were uptake in five organs and minor elimination through the gastrointestinal and urinary pathways. The data corroborates the safe use in terms of blood-brain barrier and did not show high uptake by liver. The dosimetry data support the safe use of radioactive nanoparticles as theranostic agent.
