| Abstract | ||
| Recently, nano-science is one of the most important fields. Production of nanoparticles by using microbes is a new area of interest. Therefore , this study aimed to synthesize nano-iron using Fusarium oxysporum by cell-free water extract method followed by confirmation and characterization of nano-iron by UV-visible spectrophotometry and electron microscopy. Reduction of iron ions to iron atoms was visualized through the change in the color of the mixture from pink to dark brown color with a peak at 226 nm corresponding to the Surface Plasmonic Resonance (SPR) of nano-iron by UV-Vis Spectroscopy. Transmission Electron Microscopy (TEM) showed spherical shaped nano-iron with a size range of 2.5 to 20 nm. The formation of a typical crystalline structure of iron atoms was confirmed by Selected Area Electron Diffraction (SAED). In conclusion, Fusarium oxysporum is an excellent bio-factory replacing the conventional chemical and physical techniques. | ||
