Sub-10 nm hexagonal lanthanide-doped NaLuF4 upconversion nanocrystals for sensitive bioimaging in vivo.
TL;DR: Through the use of β-NaLuF(4):Gd(3+),Yb(3 +),Tm(3+) nanocrystals as a luminescent label, the detection limit of <50 nanocrystal-labeled cells was achieved for whole-body photoluminescent imaging of a small animal (mouse) and high-contrast UCL Imaging of a whole- body black mouse with a penetration depth of ~2 cm.

Blue-Emissive Upconversion Nanoparticles for Low-Power-Excited Bioimaging in Vivo
TL;DR: Blue-emissive upconversion nanoparticles based on triplet-triplet annihilation based on TTA show low cytotoxicity and were successfully used to label living cells with very high signal-to-noise ratio and may extend the arsenal of currently available luminescent bioimaging in vitro and in vivo.

High-Efficiency Upconversion Luminescent Sensing and Bioimaging of Hg(II) by Chromophoric Ruthenium Complex-Assembled Nanophosphors
TL;DR: The nanoprobe N719-UCNPs has been shown to be capable of monitoring changes in the distribution of Hg(2+) in living cells by upconversion luminescence bioimaging.

Single upconversion nanoparticle imaging at sub-10 W cm−2 irradiance
TL;DR: This systematic study of upconversion nanoparticles reveals power-dependent luminescence enhancement from the inert shell, which explains the discrepancy in enhancement factors reported by ensemble and previous single-particle measurements.
