摘要:
The present invention relates to magnetic particle dispersions comprising coated individual monocrystalline and/or polycrystalline nanoparticles of iron oxides and nanoparticulate aggregates (multi-core particles) thereof with improved nonlinear magnetization behavior and improved heating properties in alternating magnetic fields. When measured in a magnetic particle spectrometer (MPS) the particle dispersions show a pronounced overtone structure, especially in the higher harmonics, which surpasses all previously known particle systems many times over. Therefore, the dispersions are especially useful for applications such as MPI (magnetic particle imaging). In addition, the new particle dispersions are suitable for applications in therapeutic hyperthermia, particularly passive partial-body hyperthermia or cell tracking and magnetic resonance imaging (MRI). Hence, the diagnostic and therapeutic use of the dispersions as well as pharmaceutical compositions of diagnostic or therapeutic interest comprising these dispersions are also objects of the present invention.
摘要(中):
本发明涉及包含铁氧化物和纳米颗粒聚集体(多芯颗粒)的涂覆的单个单晶和/或多晶纳米颗粒的磁性颗粒分散体,其具有改进的非线性磁化行为和交替磁场中改进的加热性能。 当在磁性粒子光谱仪(MPS)中测量时,颗粒分散体显示明显的泛音结构,特别是在高次谐波中,超过所有先前已知的粒子系统多次。 因此,分散体对于诸如MPI(磁性颗粒成像)的应用尤其有用。 此外,新的颗粒分散体适用于治疗性高热,特别是被动部分身体高热或细胞跟踪和磁共振成像(MRI)。 因此,分散体的诊断和治疗用途以及包含这些分散体的诊断或治疗感兴趣的药物组合物也是本发明的目的。
