Self-assembled complex including one or more of cobalt, silver, gadolinium, or iron

Abstract

The present disclosure relates to a self-assembled complex composed of substances existing in a body and using the same as ligands, the self-assembled complex including: metal ions including one or more of cobalt (Co), silver (Ag), gadolinium (Gd), or iron (Fe); and one or more ligands that are self-assembled with the metal ions, wherein: the self-assembled complex is reversibly self-assembled or self-disassembled; self-assembly is performed by one or more of a concentration of the metal ions or a concentration of the ligand; and the form of the self-assembled complex is controlled depending on a combination of the ligands.
