The present study reports a new approach for synthesizing (111)In-radiolabeled biocompatible Fe3O4 nanoparticles. Radioactive (111)In is doped in situ into the lattice of Fe3O4 nanoparticles to achieve robust radiolabeling for accurately tracing PEGylated Fe3O4 particles in vivo.
本研究报告了一种合成(111)铟标记的生物相容性四氧化三铁纳米颗粒的新方法。放射性(111)铟原位掺杂到四氧化三铁纳米颗粒的晶格中,以实现稳定的放射性标记,从而在体内精确追踪聚乙二醇化的四氧化三铁颗粒。
