Nanokristalle für die Magnetfeldorientierung – Biogenese von Magnetosomen

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.
