A Comparison between Chemical Synthesis Magnetite Nanoparticles and Biosynthesis Magnetite [PDF]

open access: yesBioinorganic Chemistry and Applications, 2014
The preparation of Fe3O4from ferrous salt by air in alkaline aqueous solution at various temperatures was proposed. The synthetic magnetites have different particle size distributions. We studied the properties of the magnetite prepared by chemical methods compared with magnetotactic bacterial nanoparticles.
