Ecofriendly Sweet Scented Osmanthus Leaf Extract Mediated Synthesis of Silver Nanoparticles (SNPs)

A non-toxic, ecofriendly method was used to synthesize colloidal solutions of silver nanoparticles in this study by using Sweet scented osmanthus leaf extract as the reducing and stabilizing agent at different temperatures (25°C, 40°C and 60°C) for the first time, hence, there was no need for toxic and costly reducing and capping agents, thus no chemical was used in the synthesis. The formation of silver nanoparticles was monitored by UV–Vis spectrophotometer analysis. The synthesized silver nanoparticles were characterized by; X ray Diffraction (XRD), Fourier Transfer Infrared Spectroscopy (FTIR), Scanning Electron Microscope (SEM), Thermo gravimetric analyzer (TGA) and Zetasizer Nano. The characterization shows that the synthesized nanoparticles were spherical in shape and have a size range between 13.54nm to 18.17nm. It also confirmed that the silver nanoparticles have a face cubic crystal (FCC) structure and were capped by biomolecules from osmanthus leaf extract.
