The present invention is a water-soluble magnetic or metal oxide nanoparticles, characterized in that the magnetic or metal oxide nanoparticles are coated with a phase transfer ligand composed of an attachment region, an attachment region-crosslinking region or an attachment region-active component binding region, and (1) Synthesizing water-insoluble magnetic or metal oxide nanoparticles in an organic solvent; (2) dissolving the water-insoluble magnetic or metal oxide nanoparticles in a first solvent and dissolving a phase transition ligand in a second solvent; (3) mixing the two solutions according to step (2) to replace the surface of the water-insoluble magnetic or metal oxide nanoparticles with a phase transition ligand, and separating the magnetic or metal oxide nanoparticles coated with the phase transition ligand. It relates to a method for producing water-soluble magnetic or metal oxide nanoparticles.n n n n Phase Transition Ligands, Water Soluble Magnetic Nanoparticles, Water Soluble Metal Oxide Nanoparticles |
