Cell uptake and intracellular fate of phospholipidic manganese-based nanoparticles.

During the last decades, several studies have proposed manganese (Mn) complexes as alternative contrast agents for magnetic resonance imaging (MRI). With the nanotechnology surge in recent years, different types of Mn-based nanoparticles (Nps) have been developed. However, to design effective and safe administration procedures, preliminary studies on target cells, aimed at verifying their full biocompatibility and biodegradability, are mandatory.
