Abstract :
Nanotechnology has emerged as a promising field for the development of advanced materials with diverse applications. In recent years, the synthesis of nanoparticles using eco-friendly and sustainable approaches has gained considerable attention. This study presents a novel method for the green synthesis of zinc oxide nanoparticles (ZnO NPs) using the medicinal plant Butea monosperma as a reducing and stabilizing agent. The process involved the collection and preparation of Butea monosperma leaf extracts, rich in bioactive compounds like flavonoids and phenolics. The reduction of zinc ions and subsequent nanoparticle formation were achieved by adding the leaf extract to a zinc precursor solution under optimized reaction conditions. The reaction progress was monitored using UV-Visible spectroscopy, and the characteristics of the synthesized ZnO NPs were analyzed using various techniques, such as X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), and Fourier-transform infrared spectroscopy (FTIR). The results revealed the successful green synthesis of highly stable and uniformly dispersed ZnO nanoparticles with an average size in the nanoscale range. XRD analysis confirmed the crystalline nature of the ZnO nanoparticles, and TEM images showed spherical morphology with an average particle size of approximately 30-50 nm. Furthermore, the green-synthesized ZnO nanoparticles exhibited excellent biocompatibility and demonstrated potential antibacterial activity against Gram-positive and Gram-negative bacterial strains. These findings highlight the promising biomedical applications of the eco-friendly ZnO nanoparticles derived from Butea monosperma, including drug delivery, wound healing, and antimicrobial agents. This study demonstrates an environmentally benign and cost-effective approach for the synthesis of ZnO nanoparticles using Butea monosperma, harnessing the therapeutic properties of medicinal plants for nanomaterial production. The green synthesis process offers a sustainable alternative to conventional chemical methods, reducing the environmental impact associated with nanoparticle synthesis. Further research could explore the scope of these nanoparticles for various biomedical, agricultural, and industrial applications, opening up new avenues in nanotechnology and green chemistry.
