Researchers have shown significant interest in the creation of sustainable green techniques for synthesising metal oxide nanomaterials past few years. Plant-mediated production is considered an affordable and feasible alternative to traditional physical chemical approaches. This study presents a straightforward approach environmentally friendly copper nanoparticles (CuO NPs) by solution combustion technique utilising Jasminum sambac Flower Extract. The CuO NPs produced during biosynthesis were analysed using UV-Vis, XRD, FT-IR, SEM, TEM, HPLC, BET EDX techniques. SEM pictures reveal that fragments possess sponge-like structure characterised substantial surface area. An investigation into photocatalytic activity shows they are effective as catalyst breakdown methylene blue (MB) when exposed UV solar radiation. Furthermore, demonstrated pH dependence MB. According study, best starting concentration dye breaking down things completely 2.5 parts per million (ppm), which results remarkable 79 % disintegration rate. findings indicate ability effectively treat water decomposing contaminants such blue, providing method treating wastewater.

This study focuses on developing a rapid, easy-to-use, and sensitive sensor for the electroanalytical detection of Metaxalone (MXL) first time. A novel was created by combining sulfur-incorporated graphitic carbon nitride (S-GCN) with tungsten-doped titanium oxide nanoparticles (W: TiO2 NPs) in paste, which then loaded into polytetrafluoroethylene (PTFE) tube. The synthesized modifiers were characterized using SEM, XRD, FTIR techniques to understand their structural, morphological, functional features, contributing electrocatalytic activity modified TiO2/S-GCN@CPE). Comparative analysis showed that W: TiO2/S-GCN@CPE achieved higher currents than unmodified paste electrode (CPE). Cyclic voltammetry (CV) square wave (SWV) used detect quantify MXL electrochemically. electrode's physicochemical properties studied under optimal conditions within potential range 0.3 V 1.5 V. limit 0.85 x 10-8 M demonstrated linearity over concentration 0.1–100 10-7 M. sensor's selectivity against interference from metal ions also assessed. In practical applications, developed effectively detected spiked water, tablets, biological samples, showing significant capacity good recovery rates. Additionally, stability across multiple measurements, positioning as promising detection.

Over the past decade, attention of researchers has been drawn to materials with enzyme-like properties substitute natural enzymes. The ability nanomaterials mimic enzymes makes them excellent enzyme mimics; nevertheless, there is a wide berth for improving their activity and providing platform heighten potential. Herein, we report green facile route Tectona grandis leaves extract-assisted synthesis silver nanoparticles (Ag NPs) decorated on Mg-Al layered double hydroxides (Mg-Al-OH@TGLE-AgNPs) as nanocatalyst. Mg-Al-OH@TGLE-AgNPs nanocatalyst was well characterized, average crystallite size Ag NPs found be 7.92 nm. peroxidase-like in oxidation o-phenylenediamine presence H2O2 an intrinsic property In addition, use extended towards quantification Hg2+ ions which showed linearity concentration range 80–400 μM limit detection 0.2 nM. Additionally, synergistic medicinal phytochemicals present extract demonstrated notable antibacterial against Gram-negative Escherichia coli Gram-positive Bacillus cereus.
