Provided is a novel nanoparticle, a contrast agent for magnetic resonance imaging containing the same, and a ligand compound used for production of the nanoparticle. The present invention relates to a nanoparticle including: a metal particle containing iron oxide; and a ligand which is bound to a metal atom on a surface of the metal particle and is represented by formula (3): 

Nanoparticle, contrast agent for magnetic resonance imaging containing same, and ligand compound

In order to provide g-CNcapable of being simply and easily handled, a g-CNfilm is produced by heating, as a starting material, a compound represented by XY, wherein Xis a guanidium ion or the like ion, and Yis an anion, to vaporize the compound or its reactant, and depositing the compound or the reactant over a surface of a base material heated, the surface carrying negative electric charges or having &#x3c0; electrons, so that the compound or the reactant is polymerized on the base material to generate g-CN.
