Due to Plumbago zeylanica own ecological features and environmental management applications, biological synthesis of silver nanoparticles (AgNPs) has become increasingly intriguing. Moreover, the green synthesis of AgNPs using Plumbago zeylanica aqueous extract—being a medicinal plant rich with bioactive compound—has been the main focused in this study The reduction of silver ion into nanoparticle was carried out with the aid of plant extract as Stabilizing and reducing agent., there are produced AgNPs without the involvement of any toxic chemical agent Build. The morphology, size, and crystal structure detection for synthesized AgNPs were characterized using fully automated X-ray diffraction (XRD), transmission electron microscopy  (TEM), and UV-Vis spectroscopy. The use of said AgNPs in environmental remediation, especially water treatment, is investigated. The bactericidal properties of AgNPs were tested against waterborne pathogens indicating that the formation of microbial biofilms can be prevented effectively since the number of viable microorganisms was significantly reduced. In addition, the similarity between the enzymes in various living systems resulted in high biological activity and function through a catalytic process as an aid to degrade organic pollutants which are inclusive of dyes and heavy metals. Furthermore, this green methodology for synthesizing AgNPs presents an economically and ecologically facile route for their large-scale production. Thus, Plumbago zeylanica-fabricated AgNPs can potentially help in mitigating environmental pollution; thus providing new strategies for pollution control measures and water treatment.
