Magnetic properties of magnetite synthesized by ...

2015-8-15  Magnetic nanoparticles have possible wide applications for various industrial and medical usages such as drug delivery and so on. Magnetotactic bacteria (MTB) are microorganisms that contain magnetic nanoparticles of magnetite (Fe 3 O 4) or greigite (Fe 3 S 4) enclosed in a phospholipid bilayer. The nanoparticles form chain-like organelles known as “magnetosomes.”
