    • PURPOSE: A transition metal oxide/tantalum oxide core/shell nanoparticle is provided to be used as an X-ray CT contrast agent and an MRI T2 contrast agent by combining a biocompatible molecule or ligand on the surface of a tantalum oxide shell. CONSTITUTION: A core/shell nanoparticle comprises a transition metal oxide core and a tantalum oxide shell. The transition metal oxide is selected from ferric oxide, manganese oxide, ceria, titanium oxide, nickel oxide, cobalt oxide, and zinc oxide. The size of the transition metal oxide is 1-100 nm, and the thickness of the tantalum oxide shell is 1-50 nm. A silane group or a phosphine group is combined to the surface of the tantalum oxide shell, and a functional material is combined to the silane group or the phosphine group. The functional material is selected from a biocompatible material, organic dye, a bioactive material, a functional group, an organic molecule, organic metal, a nanoparticle, a shell structure, or a combination thereof.
    • 目的:提供过渡金属氧化物/氧化钽核/壳纳米颗粒作为X射线CT造影剂和MRI T2造影剂,通过在氧化钽壳的表面上结合生物相容性分子或配体。 构成:核/壳纳米颗粒包含过渡金属氧化物核和氧化钽壳。 过渡金属氧化物选自氧化铁,氧化锰,二氧化铈,氧化钛,氧化镍,氧化钴和氧化锌。 过渡金属氧化物的尺寸为1-100nm,氧化钽壳的厚度为1-50nm。 将硅烷基或膦基与氧化钽壳的表面结合,将功能性材料与硅烷基或膦基组合。 功能材料选自生物相容性材料,有机染料,生物活性材料,官能团,有机分子,有机金属,纳米颗粒,壳结构或其组合。
