Green Synthesis of Silver Nanoparticles Utilizing Withania somnifera: Characterization and Applications

Abstract

The use of natural materials, particularly plant extracts, to produce silver nanoparticles has gained popularity as an ecologically beneficial and sustainable process known as green synthesis. Plant extracts are preferred over chemical, physical, and microbe-based approaches for biosynthetic processes. This approach is appropriate for nanoscale metal production as it does not require an aseptic environment. Nanotechnology is gaining tremendous impetus in the present century due to its capability of modulating metals into their nanosize, which drastically changes the chemical, physical and optical properties of metals. Withania somnifera, often known as ashwagandha, is a medicinal herb known for its numerous therapeutic benefits. This study investigates the green manufacture, characterization, and potential uses of silver nanoparticles (AgNPs). The green synthesis of WS-AgNPS, which provides a sustainable method of nanoparticle manufacture. The synthesised WS-AgNPs are characterised using a variety of analytical techniques, including UV-Visible spectroscopy, FTIR, XRD and TEM. Furthermore, these WS-AgNP nanoparticles have a variety of biological applications, including antibacterial activity.
