摘要
This invention provides water-soluble magnetic or water-soluble metal oxide nanoparticles, which are coated with phase transfer ligands having an adhesive region, an adhesive region-crosslinking region, or an adhesive region-reactive region, and also provides a method of preparing water-soluble magnetic or metal oxide nanoparticles, the method including (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 transfer ligand in a second solvent; and (3) mixing the two solutions achieved in step (2) to thus exchange the surface of the water-insoluble magnetic or metal oxide nanoparticles with the phase transfer ligand. Further, the water-soluble magnetic and water-soluble metal oxide nanoparticles coated with the phase transfer ligand can be used in various fields, including the separation and detection of materials, the diagnosis and treatment of diseases, and the decomposition of microorganisms and contaminants.
