Abstract :Silver nanoparticles insert ignore into journalissuearticles values(Ag-NPs); have gained immense attention among the variety of metallic nanoparticles during the past decades. In addition to the distinctive optical and electrical properties, Ag-NPs have been particularly employed for their biocidal features in industrial products, especially in biomedicine. Despite the wide range of studies and applications of Ag-NPs, yet serious limitations remained unsolved such as environmental toxicity caused by the reaction byproducts. In the present study, Ag-NPs synthesized by chemical synthesis as well by green synthesis method as a safer alternative considered as environmentally friendly, cost effective and easy-to-handle. Sodium borohydride insert ignore into journalissuearticles values(NaBH4); and the natural essential oils originating from rosemary insert ignore into journalissuearticles values(Rosmarinus officinalis); and grape seed insert ignore into journalissuearticles values(Vitis Vinifera); used as synthetic and bio-reducing agents, respectively. An ultraviolet-visible insert ignore into journalissuearticles values(UV-Vis); and X-ray Diffraction insert ignore into journalissuearticles values(XRD); spectroscopy analysis were performed, providing an insight into the composition of the Ag-NPs. Ultimately, the antimicrobial activity of the nanoparticles was tested on a gram-negative bacterium, Escherichia coli insert ignore into journalissuearticles values(E. coli);. The results revealed that Ag-NPs can be synthesized by a sustainable alternative method with the usage of essential oils originating from rosemary and grape seed, and the resultant Ag-NPs exhibit enhanced the antimicrobial activity compared to the ones synthesized by the chemical reduction method.
