Abstract

The magnetic particle spectrum (MPS) of bacterial magnetosomes, isolated from Magnetospirillum gryphiswaldense, is measured and compared to that of the current “gold standard”, Resovist®. It is shown that the amplitudes of the magnetosomes’ harmonics by far exceed that of Resovist®; the amplitude of the third harmonic is higher by a factor of 7, and is the highest value obtained for iron oxide nanoparticles to date.
