Stem Cell Labeling using Polyethylenimine Conjugated (α-NaYbF(4):Tm(3+))/CaF(2) Upconversion Nanoparticles

We report on a polyethylenimine (PEI) covalently conjugated (α-NaYbF4:Tm(3+))/CaF(2) upconversion nanoparticle (PEI-UCNP) and its use for labeling rat mesenchymal stem cells (rMSCs). The PEI-UCNPs absorb and emit near-infrared light, allowing for improved in vivo imaging depth over conventional prob...
