GOLD NANOCLUSTER MAGNETIC BODY DOPED WITH DISSIMILAR METAL ATOM, AND PREPARATION METHOD THEREFOR

摘要

The present invention relates to a gold nanocluster magnetic body doped with a dissimilar metal atom, a preparation method therefor, and a magnetic resonance imaging contrast agent that employs same, and, specifically, the present invention relates to: a gold nanocluster magnetic body doped with a dissimilar metal atom, the magnetic body having excellent magnetic characteristics, and having completely uniform size and structure so as to have a very clear spin form and excellent dispersibility in a solution; a preparation method therefor; and a magnetic resonance imaging contrast agent that employs same.
