Bacterial magnetosomes: microbiology, biomineralization and biotechnological applications

Applied 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).

Localized iron accumulation precedes nucleation and growth of magnetite crystals in magnetotactic bacteria

Scientific Reports, 2017
Many magnetotactic bacteria (MTB) biomineralize magnetite crystals that nucleate and grow inside intracellular membranous vesicles that originate from invaginations of the cytoplasmic membrane.

Magnetosome-Based Immunosensors for Foodborne Pathogen Detection

Chemosensors
Foodborne illnesses remain a global challenge, requiring rapid and sensitive detection platforms. We developed a magnetosome-based electrochemical immunosensor for lipopolysaccharide (LPS) antigens from Escherichia coli and Salmonella typhimurium ...
