CT/MRI dual-modality molecular imaging contrast agent and method for manufacturing the same

摘要

The present invention relates to a CT/MRI dual modality molecular imaging contrast agent and a method for manufacturing the same. In the present invention, the CT/MRI dual modality molecular imaging contrast agent comprises: an FePt nanoparticle; and a surface modification molecular binding to a surface of the FePt nanoparticle to modify the FePt nanoparticle with an amino-group, a carboxyl-group, or a biotin, wherein the FePt nanoparticle is in a form of sphere, octapod, cuboctahedron, cube, or truncated cube, and the FePt nanoparticle is represented by the following formula (I):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ Fe x Pt 100-x €ƒ€ƒ€ƒ€ƒ€ƒ(I)
wherein, x is 30ˆ¼60.
