Abstract

Alphaproteobacteria of the genus Magnetospirillum use dedicated organelles, the magnetosomes, to navigate along geomagnetic field lines in their natural environment. Magnetosomes are nanocrystals of magnetite (Fe3O4) which are biomineralized within specific membrane vesicles and become aligned into chains by a dedicated cytoskeleton. This article also highlights the potential for functionalization and application of these bacterial magnetic nanoparticles.
