Abstract The detection of total antioxidant capacity (TAC) in teas and its vital indicator for monitoring the fermentation degree during black tea processing are great significance intelligent manufacturing industry. Here, highly dispersed manganese species on Co‐MOF with hollow structures (HS‐Mn/Co‐MOF) nanozyme superior oxidase‐like activity is constructed colorimetric ascorbic acid (AA) TAC. Owing to Mn doping unique structures, HS‐Mn/Co‐MOF possesses more surface active oxygen species, negative charges rapid mass transport, thus resulting 20‐times higher catalytic 30‐times reaction rate than that pure Co‐MOF. Thanks remarkable activity, nanozyme‐based sensor exhibits a wide linear range 0.01–120 µ m , along low limit 3 n AA detection. Additionally, determination TAC levels real samples further achieved different types can be effectively distinguished by utilizing nanozyme. Identification prediction quality process using combined machine learning realized first time.

Abstract Metal‐halide perovskites have become attractive nanomaterials for advanced biosensors, yet the structural design remains challenging due to trade‐off between environmental stability and sensing sensitivity. Herein, a trinity strategy is proposed address this issue by integrating Mn (II) substitution with CsPb 2 Cl 5 inert shell NH ‐PEG‐COOH coating designing 2+ ‐doped CsPbCl 3 /CsPb core/shell hetero perovskite nanocrystals (PMCP PNCs). The isolates emissive core from water d–d transition generates photoluminescence long lifetime, endowing capped PNCs robust oxygen‐sensitive property. Given integration, photoluminescent hydrogel biosensors are designed embedding PMCP into system deliver on‐site pesticide information on food products. Impressively, benefiting dual enzyme triggered‐responsive property of PNCs, biosensor endowed ultra‐high sensitivity toward chlorpyrifos at nanogram per milliliter level. Such PNCs‐based sensor can provide accurate while guiding construction upcoming applications.

Abstract Halogen‐mixed CsPb(Br/I) 3 perovskite quantum dots (PeQDs) embedded glass can address the issue of stability, but suffers from low photoluminescence yields (PLQYs) for hindered in situ nucleation/growth inside robust network. Uncovering exact mechanism is highly desirable to develop high‐performance @glass commercial applications, topic remains unexplored. Here, based on femtosecond transient (fs‐TA) absorption, temperature‐dependent PL spectra, and theoretical calculations, a comprehensive understanding heat‐treatment (HT) temperature‐induced modification microstructures carrier dynamics build. It evidenced that high‐temperature HT will promote more I − ions diffusion matrix into lattice, leading retarded hot (HC) cooling, improved exciton recombination. This attributed synergistic effect reduced mass, weakened carrier‐phonon coupling, inhibited Klemens channel, eliminated defect states. Revealing these underlying mechanisms empower exert precise control optimize PLQY up near unity.
