Synthesis of the bacterial magnetosome: the making of a magnetic personality [PDF]

, 2010
Magnetotactic bacteria synthesize intracellular, enveloped, single magnetic domain crystals of magnetite Fe3O4, Fe2+Fe23+O4) and/or greigite (Fe3S4) called magnetosomes.

Structure and evolution of the magnetochrome domains: no longer alone [PDF]

, 2014
Magnetotactic bacteria (MTB) can swim along Earth's magnetic field lines, thanks to the alignment of dedicated cytoplasmic organelles. These organelles, termed magnetosomes, are proteolipidic vesicles filled by a 35–120 nm crystal of either magnetite or ...

Magnetotaxis.

Science progress, 1991
The ability of magnetotactic bacteria to orientate and navigate along geomagnetic lines is due to intracellular magnetic particles. These are enclosed within a membrane to form a magnetosome, a specialized organelle of magnetotactic organisms. The magnetic crystallite of many of the magnetotactic bacteria and algae is the iron oxide magnetite (Fe3O4 ...

Biomimicry of Magnetotactic Bacteria Via Self‐Organized Soft Matter Dispersions

Advanced Physics Research, Volume 4, Issue 10, October 2025.
Self‐assembled ferrofluid droplet chain coated with a lipid bilayer, mimicking the structural, functional and dynamic properties of magnetotactic bacteria. The controlled magnetic responsiveness suggests applicational potential of these soft matter systems in biosensing, targeted delivery, and magnetic‐responsive materials.

Efficient Use of Bio-Inspired Nanofabrication in Soft Electronics [PDF]

, 2015
Self-assembly plays an important role in the formation of different nanostructures either organic or inorganic. Controlled assembly of molecules into higher ordered hierarchical structures on the other hand require a thorough insight into the interactive

High-Fidelity Archeointensity Results for the Late Neolithic Period From Central China [PDF]

, 2020
Archeomagnetism focuses on exploring high-resolution variations of the geomagnetic field over hundreds to thousands of years. In this study, we carried out a comprehensive study of chronology, absolute and relative paleointensity on a late Neolithic site

Magnetotaxis as a Means for Nanofabrication

International Journal of High Speed Electronics and Systems, 2014
Magnetotactic bacteria (MTB), discovered in early 1970s contain single-domain crystals of magnetite ( Fe 3 O 4) called magnetosomes that tend to form a chain like structure from the proximal to the distal pole along the long axis of the cell. The ability of these bacteria to sense the magnetic field for displacement, also called magnetotaxis, arises ...

Sclerite formation in the hydrothermal-vent “scaly-foot” gastropod — possible control of iron sulfide biomineralization by the animal [PDF]

, 2006
A gastropod from a deep-sea hydrothermal field at the Rodriguez triple junction, Indian Ocean, has scale-shaped structures, called sclerites, mineralized with iron sulfides on its foot.

Light‐Emitting Diodes as Wireless Optical Transducers of Chemical Information

ChemPhotoChem, Volume 9, Issue 9, September 2025.
The synergy of light‐emitting diodes (LEDs) and bipolar electrochemistry has been explored to develop novel and straightforward optical readouts of chemical information. These approaches offer the possible encoding of the chemical information on the intensity of the light emission, opening multiple applications ranging from electroanalysis to dynamic ...
