Theranostics is a concept of integrating imaging and therapy into a single platform for use in
the next generation of personalized medicine to meet the challenges in modern health …

The misuse of chemicals in agricultural systems and food production leads to an increase in
contaminants in food, which ultimately has adverse effects on human health. This situation …

A photon avalanche (PA) effect that occurs in lanthanide-doped solids gives rise to a giant
nonlinear response in the luminescence intensity to the excitation light intensity. As a result …

The development of precision nanomedicines to direct nanostructure-based reagents into
tumour-targeted areas remains a critical challenge in clinics. Chemical reaction-mediated …

Lanthanide-doped upconversion nanoparticles (UCNPs) have attracted considerable
interest due to their superior physicochemical features, such as large anti-Stokes shifts, low …

We present a systematic study on the effect of surface ligands on the luminescence
properties and colloidal stability of β-NaYF4: Yb3+, Er3+ upconversion nanoparticles …

Upconversion nanoparticles (UCNPs) are attractive candidates for energy transfer-based
analytical applications. In contrast to classical donor–acceptor pairs, these particles contain …

For a long time, optical imaging of the deep brain with high resolution has been a challenge.
Recently, with the advance in second near‐infrared (NIR‐II) bioimaging techniques and …

Since selective detection of multiple narrow spectral bands in the near-infrared (NIR) region
still poses a fundamental challenge, we have, in this work, developed NIR photodetectors …

Wound healing is a complex process that requires effective management to prevent
infections and promote efficient tissue regeneration. In recent years, upconversion …
