Nanoparticles have become a matter of great interest in the recent times due to their unique properties and varied applications in different fields. Although there exist an array of physical and chemical methods for nanoparticle synthesis, the industry is on a lookout for a cleaner and greener alternative route for the production of nanoparticles. Synthesis of nanoparticles using microbial or phytochemical route have gained importance in this regard. This study focuses on biogenic production of silver nanoparticles. The aqueous seed extract of Trachyspermum roxburghianum was used for one step synthesis or biosynthesis of silver nanoparticles. The phytochemicals or the secondary metabolites present in the seed extract act as reducing agent and capping agent for producing zero-valent metal (ZVM) silver nanoparticles. The synthesized Silver nanoparticles were characterized by UV-VIS Spectrophotometer, X-Ray Diffraction (XRD), Fourier Transform Infra Red spectroscopy (FTIR) and Field Emission Gun-Scanning Electron Microscope (FEG-SEM). Silver nanoparticles have garnered a lot of attention as antimicrobial agent and thus bear significance in the field of Nutraceutical and food storage & packaging. However, the use of nanosilver in food coating is in its quiescent stage in nutraceutical delivery and nano carriers.

Keywords: Silver Nanoparticles, Biosynthesis, Trachyspermum Roxburghianum, Field Emission Gun-Scanning Electron Microscope (FEG-SEM).
