The burgeoning field of nanotechnology continually seeks sustainable and eco-friendly methods for nanoparticle synthesis to circumvent the environmental and biological drawbacks associated with conventional physical and chemical approaches. This study presents a novel, cost-effective, and environmentally friendly synthesis route for copper nanoparticles (CuNPs) utilizing the root extract of Rheum ribes L., a medicinal plant renowned for its rich phytochemical profile. The proposed biosynthesis method leverages the natural reducing and capping capabilities of the plant's secondary metabolites, thereby eliminating the need for harsh chemical reagents [1,2]. In this investigation, the ethanolic extract of Rheum ribes L. root was employed as both a reducing and stabilizing agent in reactions with various copper salts. The formation of CuNPs was initially confirmed by a visible color change in the reaction mixture to a characteristic yellowish-brown, and further verified by UV-Vis spectroscopy, which exhibited a distinct surface plasmon resonance (SPR) band in the range of 256-430 nm [3]. Characterization of the synthesized CuNPs was performed using X-ray diffraction (XRD) to confirm crystalline nature, scanning electron microscopy (SEM) to investigate morphology and size distribution, and Fourier-transform infrared spectroscopy (FTIR) to identify functional groups. X-ray Diffraction (XRD) analysis confirmed the crystalline nature of the biosynthesized CuNPs, revealing a facecentered cubic (fcc) structure, with an average crystallite size estimated using the Debye-Scherrer equation to be approximately 33.06 nm. The study underscores the potential of Rheum ribes L. root extract as an efficient bioresource for producing stable CuNPs, which may find applications in antimicrobial therapies, catalytic processes, and environmental remediation. This green synthesis approach not only reduces environmental impact but also offers a scalable and cost-effective route for nanoparticle production, aligning with sustainable development goals in nanotechnology [4]
