Summary: The study presents an example of near-infrared light-triggered enantioselective photopolymerization reactions using NaYF4 nanophosphors and chiral silver nanoparticles, resulting in a polydiacetylene film with high optical activity and chiral fluorescence. The manipulation of optical activity allows for easy control of the preferred screw direction of helical PDA chains. The proposed explanation is based on the electromagnetic field enhancement effect, which suggests that both enantioselectivity and reactivity benefit from resonance between upconverted emission and enhanced electromagnetic field near chiral AgNPs.

Summary: This study demonstrates the near-infrared light-driven reversible and dynamic photonic bandgap modulation of soft photonic crystal through the integration of core-shell upconversion nanoparticles and a novel molecular photoswitch. The intensity ratio of UV/vis luminescence emitted by the UCNPs can be controlled by changing the excitation power, leading to red-shift and blue-shift of the photonic reflection. This work provides new insights into the fabrication of 3D photonic nanostructures with tailorable functionalities for soft-matter photonics and integrated communication technologies.

Summary: Researchers have designed a cancer-activated nanomachine based on porous upconversion nanoparticles for precise phototherapy. The nanosystem contains a telomerase substrate primer and encapsulates 5-aminolevulinic acid and D-arginine. After coating with hyaluronic acid, the nanomachine can easily enter tumor cells and induce efficient accumulation of protoporphyrin IX via biosynthetic pathway. The nanomachine can respond to near-infrared light and generate active singlet oxygen through Förster resonance energy transfer. Moreover, it can relieve tumor hypoxia by converting D-arginine into nitric oxide, thereby improving the phototherapy effect.
