The pericarp of Myristica fragrans fruit extract was utilized for a low cost, eco-friendly synthesis of silver (AgNPs) and copper oxide (CuONPs) nanoparticles. The aqueous fruit extract of the plant was used as reducing and stabilizing agents for this preparation. Characterization of the biosynthesized nanoparticles was carried out using UV–Vis spectroscopy, FTIR spectroscopy and X-Ray Diffraction studies. Morphology and size of the particles was observed using Field-Emission Scanning Electron Microscopy (FESEM) and High Resolution Transmission Electron Microscopy (HRTEM). The copper and silver nanoparticles show Surface Plasmon Resonance (SPR) band at 360 and 478 nm respectively in the UV–Vis spectrum. It was observed that size of the synthesized copper oxide and silver nanoparticles are in the range 10–50 nm. The presence of copper and silver elements was confirmed from their respective EDS spectrum. Involvement of phytochemicals in the stabilization and reduction of the nanoparticles was confirmed by FTIR spectroscopy. CuONPs exhibited catalytic activity in 1,3-dipolar cycloaddition reaction between azides and terminal alkynes to form 1,2,3-triazoles. Silver nanoparticle possesses good antibacterial activity against multidrug human pathogens Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus subtilis. The present study focuses on the utilization of the less economic part of Myristica fragrans fruit's pericarp for the preparation of copper oxide and silver nanoparticles which have good catalytic and antibacterial activities.

肉豆蔻的果皮水果提取物被用于低成本，环保地合成银（AgNPs）和氧化铜（CuONPs）纳米颗粒。植物的含水水果提取物用作该制剂的还原剂和稳定剂。生物合成的纳米颗粒的表征使用紫外-可见光谱，FTIR光谱和X射线衍射研究进行。使用场发射扫描电子显微镜（FESEM）和高分辨率透射电子显微镜（HRTEM）观察颗粒的形态和尺寸。铜和银纳米颗粒在UV-Vis光谱中分别显示在360和478 nm的表面等离子体共振（SPR）带。观察到，合成的氧化铜和银纳米颗粒的尺寸在10–50 nm范围内。从它们各自的EDS光谱证实了铜和银元素的存在。通过FTIR光谱法证实了植物化学物质参与纳米颗粒的稳定和还原。CuONP在叠氮化物和末端炔烃之间形成1,2,3-三唑的1,3-偶极环加成反应中表现出催化活性。银纳米粒子对多种药物的人类病原体具有良好的抗菌活性大肠杆菌，铜绿假单胞菌，金黄色葡萄球菌和枯草芽孢杆菌。本研究的重点是利用肉豆蔻果实果皮较不经济的部分来制备具有良好催化和抗菌活性的氧化铜和银纳米颗粒。
