Summary: In this work, HgSe/CdSe core/shell quantum dots (QDs) emitting at 1.7 μm were synthesized with a thick shell to increase the photoluminescence quantum yield. The quantum yield was measured to be 63% in nonpolar solvents, indicating the potential for even higher quantum yield when solubilized in water. Our findings highlight the importance of a thick type-I shell for achieving bright emission in the NIR-IIb region.

Summary: Thermally activated delayed photoluminescence (TADPL) is an exotic mechanism observed in molecule-functionalized semiconductor nanocrystals, which allows for energy harvesting from dark molecular triplets and controllable, long-lived photoluminescence. Despite successful coverage of the visible spectrum, TADPL in nanocrystals is less efficient compared to thermally activated delayed fluorescence (TADF) molecules. In this study, bright, near-infrared TADPL was achieved in lead-free CuInSe2 nanocrystals functionalized with carboxylated tetracene ligands, by efficient triplet energy transfer from nanocrystals to ligands and subsequent thermally activated reverse energy transfer.

Summary: Second near-infrared window (NIR-II, 1000-1700 nm) imaging is a promising optical technique, but surface-enhanced Raman scattering (SERS)-based research in this range is limited due to the lack of suitable NIR-II Raman reporters. This study presents the first example of a nickel dithiolene complex as a NIR-II resonance Raman reporter, which exhibits intense long wavelength absorption, fluorescence-free features, and high affinity to noble metal surfaces. The developed NIR-II nanoprobes enable high contrast and highly photostable lymph node imaging, as well as in vivo SERS detection of deep-seated microtumors in mice.

Summary: Exposure to atmospheric particulate matter (PM) is a global concern due to its adverse outcomes. This study reveals that exosomes play a key role in the transfer of PM and the induction of inflammatory responses in macrophages. The release of exosomes from macrophages was stimulated by fine PM2.5, with F1 having a greater effect than F2, through regulation of the P2X7 receptor. These exosomes mediated the transfer of PM2.5 to recipient macrophages, resulting in the activation of NF-kappa B signaling and the release of inflammatory cytokines. Furthermore, these exosomes induced inflammatory responses in the lungs of mice. These findings highlight the importance of assessing exosome secretion and their impact on human health in the presence of atmospheric particulate matter.
