Core–Shell Upconversion Nanoparticle@Metal–Organic Framework Nanoprobes for Luminescent/Magnetic Dual‐Mode Targeted Imaging

Core–shell upconversion [email protected]–organic framework ([email protected]) nanostructures are constructed by coating hexagonal NaYF4:Yb,Er nanoparticle (NP) cores with amino-functionalized iron carboxylate MOF shells. These nanostructures combine the near-infrared optical property of the UCNP cores and the T2-magnetic response (MR) imaging property of the MOF shells. After surface modification, the core–shell nanostructures are demonstrated as high-resolution nanoprobes for targeted luminescence/MR imaging both in vitro and in vivo.
