Eco-Friendly Biosynthesis Of Copper Nanoparticles Using Phyllanthus Emblica And Their Characterization

Abstract

Nanotechnology has transformed numerous domains, encompassing medicine, energy, and environmental restoration, owing to the distinctive attributes of nanoparticles (NPs). Among these, copper nanoparticles (CuNPs) have attracted scrutiny for their economical viability, antimicrobial, antioxidant, and catalytic capabilities. Conventional synthesis methodologies frequently entail perilous chemicals, necessitating the pursuit of environmentally benign alternatives. This research investigates the environmentally sustainable synthesis of CuNPs utilizing Phyllanthus emblica bark extract, capitalizing on its abundant phytochemical composition as a reducing and stabilizing agent. The synthesized CuNPs were characterized employing UV-Vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), scanning electron microscopy (SEM), and X-ray diffraction (XRD). UV-Vis analysis corroborated NP formation with a surface plasmon resonance peak at 254 nm. FTIR elucidated the participation of hydroxyl, amine, and carbonyl groups in capping and stabilization. DLS indicated a Z-average dimension of 240 nm and a zeta potential of -3.44 mV, implying moderate stability. SEM imagery depicted spherical to quasi-spherical morphology with slight aggregation, while XRD validated the monoclinic crystalline architecture of CuO NPs. The research underscores the efficacy of P. emblica in generating stable, crystalline CuNPs, presenting a sustainable alternative to traditional methodologies. These NPs exhibit potential for biomedical and industrial applications, consistent with the principles of green chemistry and sustainable nanotechnology.
