Core-shell superparamagnetic nanoparticles with interesting properties as contrast agents for MRI

The effect of the core-shell NPs on the MRI contrast enhancement is obtained and quantified in a set of MRI of agar phantoms obtained at 7 T magnetic field and with a imaging gradient field of 1.6 T/m. The core-shell NPs were tested in Zebra-fish (Danio rerio) animal model. Zebra-fish MRI were obtained with animals injected with the three core-shell NPs and the contrast enhancement validated.
