    摘要: Provided is an iron oxide nanocapsule which has extremely excellent water dispersibility, which is very stable in the body and which has very excellent MRI contrast ability, a method of manufacturing the same, and an MRI contrast agent using the same. The method of manufacturing the iron oxide nanocapsule includes the steps of: thermally decomposing an iron complex to prepare hydrophobic ligand-bonded iron oxide nanoparticles; and encapsulating the hydrophobic ligand-bonded iron oxide nanoparticles by a carboxymethyldextrandodecylamine conjugate encapsulation material or a dextran-linoleic acid conjugate encapsulation material to form an iron oxide nanocapsule.

    摘要: Provided are a contrast agent for contrast imaging lymph node, which includes iron oxide nanoparticles dispersed and stabilized in an aqueous medium by a mussel adhesive protein-mimetic copolymer, a method for contrast enhanced lymphography using the foregoing contrast agent, and a method for diagnosis of lymph node cancers using the foregoing contrast agent. Using such a mussel adhesive protein-mimetic copolymer, the surface of iron oxide is modified and dispersed well in water to prepare a colloidal solution, which in turn forms the contrast agent containing the colloidal solution. The inventive contrast agent does not have toxicity and is easily taken up to the lymph node to exhibit excellent contrast imaging effects. The contrast agent of the present invention is useful for diagnosis of metastatic cancers.

    摘要: Disclosed are a composition including hydrophilic nanoparticles that have a monosaccharide-phosphate or a derivative thereof adhered to the surface thereof, a colloidal solution of the composition dispersed in water, and a magnetic resonance imaging contrast agent including the colloidal solution. According to the present invention, nanoparticles having biocompatibility and excellent water-dispersibility can be prepared by modifying the surface of inorganic nanoparticles. The prepared nanoparticles may be effectively used in a variety of applications including, for example, in vivo imaging applications such as an MRI contrast agent, nano-electronic convergence technologies such as a quantum dot light emitting device, biomedical applications such as hyperthermia, or the like. Moreover, compared to existing nanoparticles dispersed by a dispersion stabilizer known in the art, excellent dispersion stability and a relatively small hydrodynamic diameter may be attained.
