Silver nanoparticles has been used since ages, even till now it is exploited in almost all areas like medicine, textiles, industries, cosmetics, purification, dying and many more. There are many approaches which are used to synthesize silver nanoparticles. However, these approaches are either harmful to the environment or very costly. Therefore, green synthesis of silver nanoparticles (AgNPs) using leaves of Filicium decipiens eco-friendly and a very reliable method to procure AgNPs. Characterization of synthesized AgNPs were then done using UV-Vis spectroscopy and fluorescence which confirmed the formation of AgNPs, scanning electron microscope (SEM)confirmed its shape to be round and X-ray diffraction (XRD) determined its crystalline nature as face centered cubic structure. Furthermore, Dynamic Light Scattering (DLS) was also done in order to know the average diameter and zeta potential of AgNPs. However, it did not show potential results due to the aggregates formed during the green synthesis of AgNPs. In addition to this, anti-microbial test against bacteria such as gram negative (Escherichia. Coli) and gram positive (Bacillus.spc) were done using well-diffusion method and also its application of antimicrobial activity was tested over fabric to understand its application in textile industries. In both the cases, AgNPs showed more efficiency in gram negative bacteria than gram- positive.
