The impact of polymer coatings on magnetite nanoparticles performance as MRI contrast agents: a comparative study

摘要

BackgroundSuperparamagnetic iron oxide nanoparticles (SPIONs) are the most commonly used negative MRI contrast agent which affect the transverse (T2) relaxation time. The aim of the present study was to investigate the impact of various polymeric coatings on the performance of magnetite nanoparticles as MRI contrast agents.
