Summary: A highly selective and sensitive fluorescent sensor based on rhodamine fluorophore was developed for detecting Cu2+. The sensor displayed a strong fluorescence turn-on effect upon addition of Cu2+ and could be recognized by the naked eye. The sensor also enabled quantitative analysis of Cu2+ due to the formation of a stable 1:1 metal-ligand complex in a short time, which exhibited good pH stability. Furthermore, molecular orbital and spatial structure investigations, as well as cell imaging and zebra fish experiments, demonstrated the broader application prospects in biological systems.

Summary: Advances have been made in nanotechnology, specifically in the field of sensor analysis using gold nanoparticles (AuNPs). The ideal sensor requires characteristics such as selectivity, sensitivity, accuracy, precision, and linearity. Various methods have been used to synthesize AuNPs and combine them with other components to obtain desirable properties. AuNPs can be used for detecting heavy metals, biological molecules, and pharmaceutical compounds. The size and shape of the particles play a crucial role in their application, with spherical particles being the most suitable for achieving sensitivity and selectivity. Functionalization of AuNPs with conjugates/receptors enhances stability, sensitivity, selectivity, and solubility, especially in detecting biological compounds.

Summary: Textile industry effluents contain hazardous synthetic dyes. Layered double hydroxide based hybrid composites have been found to be efficient nanosized adsorbents for water treatment. In this study, different adsorbents and composites were prepared and characterized, and it was observed that all adsorbents showed complete dye removal within a short time. Among them, composite C2 exhibited the best dye removal performance. The pH of the adsorption medium did not significantly affect the removal efficiency, while room temperature and lower dye concentration favored adsorption. The composite demonstrated good regenerative performance and the adsorption kinetics followed a pseudo-second-order model. The Freundlich model was found to best explain the experimental data, and the adsorption of the methyl orange by g-C3N4/LDH composite was exothermic and spontaneous.
