“…Therefore, by regulating shape and size at a nanometre scale, it is possible to design and produce materials with novel uses. Nanoparticles display shape and size‐dependent properties, which are of interest for various uses such as bio‐sensing, catalysts to optics, computer transistors, antimicrobial activity, electrometers, wireless electronic logic, memory schemes, and chemical sensors (Alavi & Moradi, 2022; Dat et al ., 2023). Metal nanoparticles are extensively used in the areas of medicine and pharmacy.…”

In this study, the copper nanoparticles were synthesized using various concentrations (5%, 6 %, 8%, and 10%) of Nigella sativa seed extracts, and their antibacterial and antiobesity effect was evaluated. The optimum particle size (98.23 nm) of nanoparticles was obtained at an extract concentration of 8%. FTIR results confirmed the functional groups responsible for copper ion reduction, The synthesized nanoparticles exhibited high antibacterial activity against Pseudomonas aeruginosa and Escherichia coli having inhibition zone of 25 mm and 24 mm, respectively. Significantly (P < 0.005) percent lipase and amylase inhibition assay of copper nanoparticles confirmed their antiobesity activities.

“…Among them, metal oxide nanoparticles such as zinc oxide, tungsten trioxide, copper oxide, gold oxide, iron oxide, magnesium oxide, titanium oxide, tin oxide, silver oxide, platinum oxide, cobalt oxide and palladium oxide have attracted a lot of attention for wastewater treatment due to their superior surface functional groups, surface area, high adsorption effectiveness, chemical and thermal stability [ [28] , [29] , [30] , [31] , [32] ]. Many nanoadsorbents such as hematite iron oxide nanoparticles [ 33 ], magnesium oxide hematite nanocomposite [ 34 ], zirconium oxide [ 35 ], titanium oxide nanoparticles [ 36 ], copper oxide nanoparticles [ 37 ], graphene oxide nanoparticles [ 35 ], graphite carbon nitride [ 38 ] have been explored due to their high adsorptive capacity and effectiveness in the treatment of wastewater.…”

Amid growing environmental concerns and the need for a sustainable future, green synthetic methodologies are gaining popularity for their simplicity and nontoxicity. In pursuit of the eco‐friendly synthesis of nanomaterials, the study reports an innovative synthesis of Ag‐CuO nanocomposites via the coprecipitation method utilizing Citrus limetta fruit juice extract as the bioreductant and stabilizing agent. The morphological and structural characteristics of the fabricated nanocomposites were evaluated by ultraviolet–visible diffuse reflectance spectroscopy (UV–vis DRS), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy‐dispersive X‐ray (EDX), transmission electron microscopy (TEM), X‐ray diffraction (XRD), Raman and Brunauer–Emmett–Teller (BET) analyses. The nanocomposites were crystalline with particle sizes ranging from 15 to 24 nm and exhibited spherical and rod‐like shapes. The band gap value and specific surface area of the nanocomposites were found to be 1.5 eV and 25.50 m2/g, respectively. The photoluminescence (PL) analysis and electrochemical studies revealed significant charge separation and effective charge migration behaviour of the nanocomposites, respectively. The nanocomposites effectively catalysed the synthesis of Schiff bases from aryl aldehydes and aromatic amines at room temperature and without solvents. The reactions proceeded in a brief time with excellent product yields, and the nanocatalyst retained its activity for five consecutive cycles. The nanocomposites also efficiently catalysed the photodegradation of Congo red dye under visible light. A significant degradation of 94.33% was attained in 55 min, and the nanocatalyst maintained its efficacy over four consecutive reaction cycles. Moreover, the nanocomposites exhibited notable anticancer properties against the MCF‐7 (human breast) cell line, demonstrating a remarkable cytotoxicity rate of 87.79%. The findings highlight the efficacy of the biosynthesized nanocomposites in catalysis, environmental remediation and biological applications.
