Silver nanoparticles (Ag NPs) are widely studied and extensively used in various applications because of their superior properties. Suitable structural modification with the right synthetic method is the key to obtain superior properties of Ag NPs. In the field of nanotechnology, the development of reliable and eco-friendly methods for the synthesis of nanoparticles is crucial. The conventional methods for the synthesis of NPs are costly, toxic, and not ecofriendly. To overcome these issues, natural sources such as plant, bacteria, fungi, and biopolymers have been used to synthesize AgNPs. These natural sources act as reducing and capping agents. With the aim of promoting a green approach for the synthesis of NPs, this study describes eco-friendly method for the preparation of biogenic NPs and the known mechanisms for their biosynthesis. Silver nanoparticles (AgNPs) have been reported to form composites with polymers such as polyvinyl alcohol, polypyrrole, polyvinylidene fluoride, chitosan, and cellulose. The formation of silver/polymer nanocomposite requires that the size of nanoparticles in the polymer matrix be controllable and that their distribution within the polymer matrix be uniform. In this study, extract from “orange peels” were utilized for the synthesis of silver/PVA nanocomposite (Ag/PVA Nps) from silver nitrate solution. The bioactive components of extracts and the morphology of Ag/PVA Nps were studied using FTIR, UV-Vis spectroscopy, SEM, XRD and AFM The antimicrobial and antifungal activities were also performed
