Biocompatible and fluorescent superparamagnetic iron oxide nanoparticles with superior magnetic properties coated with charged polysaccharide derivatives
Superparamagnetic iron oxide nanoparticles labeled with cumarine were synthesized. Nanoparticels exhibit superior magnetic properties as contrast agents for MRI. They easily penetrate cell membrans and can be tracked by fluorescencje microscopy. They were shown to be non-toxic due to hyaluronic acid coating.
