ABSTRACT:
Magnetic nanoparticles are applicable in imaging, diagnosis, therapy, and biomaterial separation. The magnetic nanoparticles comprise a core represented as FexMavZyand a shell of an inner-transition element Mbor the compound thereof, wherein Mais an inner-transition element, Z is an element of the group Vla, x is greater or equal to 0, and v, y are positive numbers. The surface of the shell is optionally modified by liposome, polymer, aliphatic compound, aromatic compound or combinations thereof.
