[Aim]: To study the efficiency of multifunctional polymer-based superparamagnetic iron oxide nanoparticles (bioferrofluids) as a T2 magnetic resonance contrast agent and their uptake and toxicity in liver. [Materials & methods]: Mice were intravenously injected with bioferrofluids and Endorem®. The magnetic resonance efficiency, uptake and in vivo toxicity were investigated by means of magnetic resonance imaging (MRI) and histological techniques. [Results]: Bioferrofluids are a good T2 contrast agent with a higher r2/r1 ratio than Endorem. Bioferrofluids have a shorter blood circulation time and persist in liver for longer time period compared with Endorem. Both bioferrofluids and Endorem do not generate any noticeable histological lesions in liver over a period of 60 days post-injection. [Conclusion]: Our bioferrofluids are powerful diagnostic tool without any observed toxicity over a period of 60 days post-injection., Financial support from the Spanish Ministry of Science and Innovation research grant MAT2014-54975-R, and from the Programa Operativo FEDER Aragon 2014-2020 ‘Construyendo Europa desde Aragon’, is gratefully acknowledged.
