Magnetosome dynamics in magnetotactic bacteria
Biophysical Journal, 1984 Diffusive motions of the magnetosomes (enveloped Fe3O4 particles) in the magnetotactic bacterium Aquaspirillum magnetotacticum result in a very broad-line Mössbauer spectrum (T approximately 100 mm/s) above freezing temperatures. The line width increases with increasing temperature.

Fluidic bacterial diodes rectify magnetotactic cell motility in porous environments
Nature Communications, 2021 Microswimmers can navigate porous environments, however the impact of their directed motility on their movement in fluid flow remains an open issue. The authors show that the motility of magnetotactic bacteria in flow through a porous constriction gives ...

Magnetotactic Bacteria and Magnetosomes: Basic Properties and Applications
Magnetochemistry, 2021 Magnetotactic bacteria (MTB) belong to several phyla. This class of microorganisms exhibits the ability of magneto-aerotaxis. MTB synthesize biominerals in organelle-like structures called magnetosomes, which contain single-domain crystals of magnetite ...

Membrane vesicles in magnetotactic bacteria
Microbiological Research, 2003 Magnetotactic bacteria are microorganisms that respond to magnetic fields. We have studied the surface ultrastructure of Magnetospirillum magnetotacticum and uncultured magnetotactic bacteria from a marine environment using transmission electron microscopy and freeze-etching.

Magnetotactic Bacteria as Potential Sources of Bioproducts
Marine Drugs, 2015 Magnetotactic bacteria (MTB) produce intracellular organelles called magnetosomes which are magnetic nanoparticles composed of magnetite (Fe3O4) or greigite (Fe3S4) enveloped by a lipid bilayer.

Magnetite in Freshwater Magnetotactic Bacteria
Science, 1979 A previously undescribed magnetotactic spirillum isolated from a freshwater swamp was mass cultured in the magnetic as well as the nonmagnetic state in chemically defined culture media. Results of Mössbauer spectroscopic analysis applied to whole cells identifies magnetite as a constituent of these magnetic bacteria.

Advanced Science, EarlyView.This review surveys nanoparticle‐based strategies to enhance adoptive cell therapy, particularly CAR‐T cell approaches, in solid tumor treatment. It describes how nanoparticles can improve tumor immunogenicity and T‐cell infiltration while reducing toxicity, and how they enable in vivo CAR‐T cell generation.
