Much interest has gained the biomineralization process carried out by magnetotactic bacteria. These bacteria are ubiquitous in natural environments and share the ability to passively align along the magnetic field lines and actively swim along them.

One-dimensional magnetic nanostructures have magnetic properties superior to non-organized materials due to strong uniaxial shape anisotropy. Magnetosome chains in magnetotactic bacteria represent a biological paradigm of such magnet, where magnetite

The iron oxide mineral magnetite (Fe 3 O 4 ) is produced by various organisms to exploit magnetic and mechanical properties. Magnetotactic bacteria have become one of the best model organisms for studying magnetite biomineralization, as their genomes

Magnetotactic bacteria are Gram-negative bacteria that navigate along geomagnetic fields using the magnetosome, an organelle that consists of a membrane-enveloped magnetic nanoparticle. Magnetite formation and its properties are controlled by a speci

Inorganic Magnetite Precipitation at 25 °C: A Low-Cost Inorganic Coprecipitation Method

Autor: Concepcion Jimenez-Lopez, Alejandro B. Rodríguez-Navarro, Teresa Perez-Gonzalez

Publikováno v: Journal of Superconductivity and Novel Magnetism. 24:549-557

An easy, low-cost coprecipitation method to inorganically produce magnetite nanoparticles from solutions, in free-drift experiments, under anoxic conditions, at 25 °C and 1 atm pressure is here presented. By using this method, pure magnetite is obta
