Simple models for dynamic hysteresis loops calculation: Application to hyperthermia optimization [PDF]

open access: yes, 2010
To optimize the heating properties of magnetic nanoparticles (MNPs) in magnetic hyperthermia applications, it is necessary to calculate the area of their hysteresis loops in an alternating magnetic field.

How magnetotactic bacteria make magnetosomes queue up

open access: yesTrends in Microbiology, 2006
Magnetotactic bacteria contain chains of magnetosomes that comprise a permanent magnetic dipole in each cell. In two separate, recent papers, Scheffel et al. and Komeili et al. describe the roles of the proteins MamJ and MamK in magnetosome chain formation.

Bacterial magnetosomes: microbiology, biomineralization and biotechnological applications

open access: yesApplied Microbiology and Biotechnology, 1999
Magnetotactic bacteria orient and migrate along geomagnetic field lines. This ability is based on intracellular magnetic structures, the magnetosomes, which comprise nanometer-sized, membrane-bound crystals of the magnetic iron minerals magnetite (Fe3O4) or greigite (Fe3S4).

Magnetic iron oxide nanoparticles as MRI contrast agents - a comprehensive physical and theoretical study [PDF]

open access: yes, 2015
Magnetite nanoparticles, especially superparamagnetic iron oxide nanoparticles, are established contrast agents for magnetic resonance imaging. Magnetosomes, which are magnetite nanoparticles of biological origin, have been shown to have better contrast
