Summary: This study investigates the coassembly behavior of AuNCs modified with PRT and TA, revealing that intermolecular hydrogen bonding and pi-pi stacking are the main driving forces for the formation of ordered aggregates and the enhancement of luminescence of PRT-AuNCs. Inspired by the optical properties of the PRT-AuNCs/TA complex, a luminescent nanocomposite hydrogel with self-healing properties was successfully prepared, and a multicolor hydrogel was obtained by doping blue emission quantum dots (QDs). The different pH-responsive behaviors of QDs and PRT-AuNCs make the multicolor hydrogel a candidate for potential applications in information encryption.

Summary: Aqueous gold nanoclusters (AuNCs) have potential applications in biomedical imaging and therapy due to their unique electronic structures. However, their optical impurity and polydispersity pose challenges for isolation of the most stable structure and potential clinical applications. This study reports optically pure Au16L14 clusters, assessed by fluorescence excitation-emission matrix (EEM) spectroscopy and parallel factor (PARAFAC) analysis. The reactivity of the excited state with molecular oxygen was also investigated, showing that Au16L14 clusters generate type I reactive oxygen species (ROS), making them effective sensitizers for photodynamic therapy.

Summary: This study systematically investigated the role of sodium hydroxide in the formation and emission properties of Au nanoclusters. It was found that the activity of the gold precursor and the emission properties of the resulting Au nanoclusters depend on the addition time of sodium hydroxide. Additionally, the reducing ability of BSA is dependent on the concentration of sodium hydroxide in the reaction solution. By optimizing the addition time and concentration of sodium hydroxide used, Au nanoclusters with improved emission properties were successfully synthesized under relatively low BSA concentrations, showing improved performance in sensing Cu2+ ions.

Summary: A unique nanomaterial platform was developed for trace detection and efficient degradation of triclosan (TCS) using a silver spherical nanoparticle (AgNP)-modified ZnO multipods (ZnO@Ag) template. The ZnO@Ag template demonstrated excellent degradation and detection performance, with TCS degradation up to 92% under UV irradiation at 365 nm and a detection limit as low as 10-9 M. This is the first investigation into the use of ZnO@Ag bimetallic composites for SERS-based detection and UV-assisted degradation of environmental TCS pollutants. The technology was successfully applied to determine antibacterial agents and TCS in distilled or river water, highlighting the advantages of the ZnO@Ag template over conventional detection methods.

Summary: The aim of this study is to synthesize nanocomposites of UiO-66@ZnO/Biochar to encapsulate carbendazim (CBZ) pesticide in its porous structures for smart spraying and cleaner production. The adsorption capacities of CBZ onto UiO-66@ZnO and UiO-66@ZnO/Biochar nanocomposites in a DMSO-water mixture were found to be 68.8% and 72.6% respectively. The half-life of photodegradation rate constants for CBZ@UiO-66@ZnO/Biochar was 12.3 times longer than that of free CBZ. IC50 determination showed that CBZ@UiO-66@ZnO/Biochar inhibited the growth of Fusarium oxysporum and Aspergillus niger at concentrations of 73.8 µg/L and 209 µg/L respectively. This study provides a comprehensive experimental approach for the chemisorption process of CBZ onto UiO-66@ZnO/Biochar composite materials and the application of nanopesticides in sustainable agriculture.
