In situ111In-doping for achieving biocompatible and non-leachable 111In-labeled Fe3O4 nanoparticles†
Abstract
The present study reports a new approach for synthesizing 111In-radiolabeled biocompatible Fe3O4 nanoparticles. Radioactive 111In is doped in situ into the lattice of Fe3O4 nanoparticles to achieve robust radiolabeling for accurately tracing PEGylated Fe3O4 particles in vivo.
