Nanoparticles, nuclear magnetic resonance imaging contrast agents comprising the nanoparticles, and ligand compounds |
| abstract |
Novel nanoparticles, MRI contrast agents comprising the nanoparticles, and ligand compounds for making the nanoparticles are provided. The invention relates to a nano particle, which comprises: metal particles containing iron oxide, and a ligand represented by formula (3) bonded to metal atoms on the surface of the metal particles. (In the formula, m is an integer of 1 to 4, and the dotted line represents a coordination bond with a metal atom on the surface of the metal particle). |
