Compared with downconverters (organic dyes and quantum dots), upconverting nanoparticles (UCNPs) can switch low energy near-infrared (NIR) photons into high energy UV and/or visible photons with pronounced stability. Due to the fast advancement of colloidal synthesis techniques, lanthanide-doped UCNPs can be fabricated with narrow distribution and modulated physical behaviors. These unique characteristics allow them to outperformconventional bio-imaging materials and offer a versatile platform for biological applications. Here, we discuss several approaches to the synthesis and application ofUCNPsas imaging probes, delivery carriers and therapy sensitizers.
