Triplet states have been widely studied in phosphorescent molecules, lanthanide complexes
and triplet–triplet annihilation systems, in which they have a critical role in energy transfer …

Enzymes have received extensive research due to their high selectivity, efficiency, and
environmental protection. However, the lack of stability and reusability drastically hinders the …

Phototherapy of deep tumors still suffers from many obstacles, such as limited near-infrared
(NIR) tissue penetration depth and low accumulation efficiency within the target sites …

The field of advanced nanotechnology is brimming with a plethora of nanotheranostics
whose combinatorial synergistic applicability in treating malignant tumors is tremendous. But …

Owing to the strong absorption of water in the near-infrared (NIR) region near 1.0 μm, this
wavelength is considered unsuitable as an imaging and analytical signal in biological …

Persistent luminescence describes the phenomenon whereby luminescence remains after
the stoppage of excitation. Recently, upconversion persistent luminescence (UCPL) …

Advances in the development of new biorecognition elements, nanoparticle‐based labels as
well as instrumentation have inspired the design of new bioaffinity assays. This review …

Here, chiral second near‐infrared (NIR‐II) emitting rare‐earth doped silver selenide
nanoparticles (R‐or S‐Ag2Se: Nd/Yd/Er NPs) were fabricated, exhibiting circular dichroism …

The COVID-19 crisis requires fast and highly sensitive tests for the early stage detection of
the SARS-CoV-2 virus. For detecting the nucleocapsid protein (N protein), the most …

Photon avalanche (PA)—where the absorption of a single photon initiates a 'chain
reaction'of additional absorption and energy transfer events within a material—is a highly …
