Green Synthesis, Characterization of Nanoparticles Using Plant Extracts and Evalution of Antiviral, Antioxidant and Antimicrobial Activity

Abstract: The development of environmentally friendly methods for the synthesis of nanoparticles has proven to be a significant step forward in the field of nanotechnology. Nanotechnology is a scientific field that structures materials at the atomic level to achieve unique properties that can be manipulated for required applications. Among all metal nanoparticles, silver nanoparticles have attracted the most attention due to their unique physical, chemical and biological properties. To overcome the limitations of traditional methods for synthesizing nanoparticles, green chemistry has emerged as an alternative. The synthesis of nanoparticles using plants is considered the most suitable of all available environmentally friendly methods due to the large diversity of biomolecules present in plants, which act not only as reducing agents but also as stabilizers/limiting agents etc. to enhance the reaction speed. Moreover, unlike microbial cultures, they are easy to handle, widely used, and readily available.In this review, we consider different plants that can be used for rapid and one-step protocols for the synthesis of silver nanoparticles and also discuss their antiviral, antibacterial, and antioxidant properties.
