Green, effective biological route for the synthesis of silver nanoparticles using cyperus rotundus grass extracts

Development of consistent and eco-friendly processes for the synthesis of metallic nanoparticles is an essential requisite nowadays. Herein we present the distinct properties of the silver nanoparticles (AgNPs) synthesized using hot water Cyperus Rotundus Grass Extracts (CRGE) a reducing and capping agent. The nature of AgNPs synthesized was analyzed by Atomic Force Microscope (AFM), Scanning Electron Microscope (SEM), energy-dispersive microanalysis (EDX), X-ray diffraction spectroscopy (XRD), Flourier Transform Infra Red (FTIR), Thermo Gravimetric Analysis (TGA), Differential Thermal Analysis (DTA) and UV–vis spectroscopy (UV). UV spectral analysis showed silver surface Plasmon resonance band at 425nm. XRD showed that the particles were crystalline in nature with face centered cubic structure of the bulk silver with broad peaks at 35.62o, 38.24 o, 46.42 o, 55.00 o, 64.5 o, 78 o. Morphologically, the nanoparticles were found to be spherical with an average particle size distribution of 1 to 100 nm. CRGE demonstrated strong potential for synthesis of silver nanoparticles by rapid reduction of silver ions (Ag+ to Ago).
