Drug-loaded superparamagnetic iron oxide nanoparticles for combined cancer imaging and therapy in vivo

Multitasking rust ball: The questions of where a tumor is located, whether drugs are properly delivered to the tumor, and what the therapeutic response of the tumor is, could be answered by using simple but smart, drug-loaded superparamagnetic iron oxide nanoparticles that can accumulate in tumor with high efficiency thanks to the presence of rationally engineered polymer coating layers.
