Abstract
In current work, silver nanoparticles (AgNPs) were prepared by a rapid biogenic technique “Green method” utilizing root extract of Olea ferruginea. The synthesized nanoparticles were characterized for UV visible spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning electron microscopy (SEM), High Resolution Transmission Electron Microscopy Studies (HRTEM) and biological assays. UV visible absorption spectroscopy confirms the formation of AgNPs by giving Surface Plasmon Resonance (SPR) peak at 430 nm. FTIR study showed occurrence of various functional groups present in root extract of Olea ferruginea. X-ray diffraction analysis determined the crystalline nature of bio-fabricated silver nanoparticles. The elemental composition of green made silver nanoparticles was studied through Energy Dispersive Spectroscopy (EDS) analysis. SEM & HRTEM study revealed the size, shape, surface morphology & dispersion level of molecules. The biologically synthesized AgNPs showed high antimicrobial, antifungal and antioxidant activity. The AgNPs are observed to be an excellent catalyst on reduction of hazardous dyes, which is confirmed by a decrease in absorbance of maximum values.
