Magnetic nanoparticles with fluorescent properties and specific targeting functions. The fluorescent magnetic nanoparticle includes a magnetic nanoparticle, a biocompatible polymer chemically modifying the magnetic nanoparticle, a fluorescent dye coupled to the biocompatible polymer, and a specific targeting agent coupled to the biocompatible polymer. The fluorescent and magnetic properties of the nanoparticles provide different types of signal sources and therefore, prompt imaging using different types of imaging techniques to reconfirm foci is feasible.
具有荧光特性和特定靶向功能的磁性纳米颗粒。荧光磁性纳米颗粒包括磁性纳米颗粒,化学修饰磁性纳米颗粒的生物相容性聚合物,与生物相容性聚合物偶联的荧光染料以及与生物相容性聚合物偶联的特定靶向剂。纳米颗粒的荧光和磁性特性提供了不同类型的信号源,因此,使用不同类型的成像技术进行重新确认是可行的。
