Recent Advance of Biological Molecular Imaging Based on Lanthanide-Doped Upconversion-Luminescent Nanomaterials
Lanthanide-doped upconversion-luminescent nanoparticles (UCNPs), here which can be excited by near-infrared (NIR) laser irradiation to emit multiplex light, have been proven to be very useful for in vitro and in vivo molecular imaging studies.In comparison with the conventionally used down-conversion fluorescence imaging strategies, the NIR light e
