Application
Upconversion nanoparticles (ucnps), are the result of a unique optical process in which near-infrared (NIR) light excitation is converted into visable and/or UV emission. Upconversion (UC) utilizes sequential absorption of multiple photons utilizing both lifetime and real ladder-like energy levels of ions in a host lattice to produce a higher energy anti-Stokes luminescence.
This optical features of UCNPs, results in deep tissue penetration and minimal autofluorescence background, for a broad range of applications of UCNP in diagnostics and biomedical imaging systems.
Applications include:
Fluorescent microscopy
Deep-tissue bioimaging
Nanomedicine
Optogenetics
Security labelling
Volumetric display

Upconversion nanoparticles (UCNPs) convert near-infrared into visible light at much lower excitation densities than those used in classic two-photon absorption microscopy. Here, we engineered <50 nm UCNPs for application as efficient lanthanide resonance energy transfer (LRET) donors inside living cells. By
