Summary: A soluble but non-luminous glutathione-stabilized copper nanocluster (GSH-CuNCs) was successfully fabricated using a straightforward, cost-effective and biocompatible reduction approach. When Ce3+ was injected at an extremely low concentration of only 18 μM, a remarkable fluorescence enhancement of up to 1 x 10(3) times was achieved. Ce3+ outperformed other rare-earth metal ions in inducing fluorescence amplification of the non-luminous GSH-CuNCs and was also employed as an inducer and reactant to construct a novel ensemble sensor for the detection of 2,6-pyridine dicarboxylic acid (DPA).

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.

Summary: The development of the textile industry has raised concerns due to the contamination of drinking water by organic dyes, which pose a carcinogenic risk to humans. Nanomaterials, particularly semiconductors, have been utilized for photocatalytic degradation of dye pollutants. Various parameters, such as catalyst dosage, irradiation time, light sources, initial dye concentration, temperature, and pH, play significant roles in the degradation process. Different generations of photocatalytic nanomaterials, including single metal nanoparticles, binary and ternary metal oxides, as well as inert solid substrates with photocatalysts, have been employed for dye degradation.

Summary: Panax ginseng, as an ethnomedicinal plant, has therapeutic effects in traditional medicine. This study investigated the potential use of green-synthesized silver nanoparticles from Panax ginseng leaf extract for the treatment of lung carcinoma and heart protection against mitochondrial dysfunction and cardiac dysfunction in obese insulin-resistant rats. The silver nanoparticles showed spherical morphology with a size range of 12.11 to 43.33 nm. In vivo experiments demonstrated that the silver nanoparticles significantly improved metabolic parameters, heart rate variability, cardiac function, and cardiac mitochondrial function in the rats. This study suggests that silver nanoparticles derived from Panax ginseng have cardioprotective effects.
