Lanthanide-doped core–shell nanoparticles as a multimodality platform for imaging and photodynamic therapy

Abstract

We report a novel lanthanide-doped core-shell nanostructure NaYF4:Yb,Er@NaGdF4:Nd@SiO2-RB with a unique design feature that integrates luminescence imaging in biological window II, magnetic resonance imaging, and NIR-excited photodynamic antimicrobial chemotherapy, in a single nanoscale entity.
