These magnetic particles, known as magnetosomes, help bacteria orient themselves and find their preferred environments.

Nanoparticles Take Fantastic, Magnetic Voyage

Objective: Magnetotactic bacteria (mtb) produce highly organized chains of magnetite nanoparticles within intracellular membranes called magnetosomes. The alignment of these magnetic nanoparticles endows the bacteria with a substantial magnetic dipole, Which it can use in relation to the earths magnetic field to navigate its environment.
