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.
本发明涉及一种包括亲水性纳米颗粒的组合物,其表面附着有单糖酸盐或其衍生物,以及该组合物在水中分散的胶体溶液和包括该胶体溶液的磁共振成像对比剂。根据本发明,通过修饰无机纳米颗粒的表面,可以制备具有生物相容性和优异的水分散性的纳米颗粒。所制备的纳米颗粒可在多种应用中有效使用,包括体内成像应用,如MRI对比剂,纳米电子融合技术,如量子点发光装置,生物医学应用,如超热疗等。此外,与现有的通过分散稳定剂分散的纳米颗粒相比,可以获得优异的分散稳定性和相对较小的流体动力学直径。
