Metal atom cluster-embedded magnetic iron oxide nanoparticle (mion), and preparation method and application thereof |
| abstract |
A metal atom cluster-embedded magnetic iron oxide nanoparticle (MION) is disclosed. The metal atom cluster is embedded in an iron oxide crystal matrix and has a content of 0.1% to 15%. A method for preparing the MION includes: dissolving a metal precursor of iron oxide, an organic acid, and an organic amine in an organic solvent to form a uniform reaction system; heating the reaction system to 150° C. to 350° C. in an inert gas atmosphere; adding a metal atom cluster precursor; and heating to perform a reflux reaction until the metal atom cluster precursor is completely decomposed. The MION shows improved magnetic properties due to the embedding of the metal atom cluster, and the iron oxide fully ensures the stability of properties of the nanoparticles. The nanoparticles are especially applicable to biomedical detection and therapy and other fields. |
