A study of iron oxide nanoparticles synthesis by using bacteria

Abstract

The biosynthesis of nanoparticles by using microorganisms is developing as an ecofriendly method for nanoparticle synthesis because of its cheap, simple and non-toxic. Bacillus sp. can be used for producing iron oxide nanoparticles. In addition, it has the ability for the biosynthesis of Fe3O4 nanoparticles. The nanoparticles producing was evaluated by using ultra violate-visible (UV-visible) and Fourier-transform infrared spectroscopy (FT-IR) methods also the production and size of the nanoparticle was confirmed by X-ray Diffraction and Field Emission Scanning Electron Microscope (FESEM) to confirm the accuracy of iron oxide nanoparticles. pH, Temperature, and Incubation time of production of iron oxide nano-particle also studied.
