Engineering a facile and controllable approach to modulate the spectral properties of lanthanide‐doped upconversion nanoparticles (UCNPs) is always an ongoing challenge. Herein, long‐range ordered, distinct two‐dimensional (2D) binary nanoparticle superlattices (BNSLs) composed of NaREF4:Yb/Er (RE = Y and Gd) UCNPs and plasmonic metallic nanoparticles (Au NPs), including AB, AB3, and AB13 lattices,...
Precise knowledge about optical and structural performance of individual rare earth (RE)‐doped particles is extremely important for the optimization of luminescent particles and for fully exploiting their capability as multifunctional probes for interdisciplinary applications. In this work, optical and structural anisotropy of individual particles through RE‐doped single fluoride microcrystals with...
On page 5944, T. Zhang, D. Xing, and co‐workers utilize upconversion luminescent materials to construct a new theranostic nanoprobe. This probe detects and images specific tumor‐related mRNA and monitors target‐triggered therapeutic drug release according to the mRNA expression level under near infrared (NIR) irradiation.
Remote optical detection and imaging of specific tumor‐related biomarkers and simultaneous activation of therapy according to the expression level of the biomarkers in tumor site with theranostic probes should be an effective modality for treatment of cancers. Herein, an upconversion nanobeacon (UCNPs‐MB/Dox) is proposed as a new theranostic nanoprobe to ratiometrically detect and visualize the thymidine...
