    摘要: A nanoparticle contains a core including superparamagnetic nanoparticles and having an outer surface, and siloxanyl moieties covalently coupled to the outer surface of the core and having Formula (I): In formula (I): X1 and X2 independently represent methylene, ethylene or propylene; R represents an optionally substituted pyridyl group, or —S—R is a group derived from a targeting ligand containing —SH group and effective to bind specifically with a predetermined targeted cell in an object; n and m independently represent an integer ranging from 1 to 3; and p represents an integer ranging from 9 to 45. The nanoparticles are suitable for use as a magnetic resonance imaging contrast agent.

    摘要: A ligand and a metal complex having the ligand are provided. The ligand and a paramagnetic metal ion form a metal complex with high stability, high relaxivity and high biocompatibility. The metal complex of the present invention is applicable to the preparation of MRI contrast agents for detecting atherosclerosis. The MRI contrast agent includes a peptide sequence specific to a matrix metalloprotease, and can be recognized by a pathological thrombocyte to target a specific site, so as to enhance the imaging contrast.
