Elucidating the role of shape anisotropy infaceted magnetic nanoparticles using biogenicmagnetosomes as a model
(Royal Society of Chemistry, 2020-08-14)
Shape anisotropy is of primary importance to understand the magnetic behavior of nanoparticles, but a rigorous analysis in polyhedral morphologies is missing. In this work, a model based on finite element techniques has ...
Magnetosomes could be protective shields against metal stress in magnetotactic bacteria
(Nature, 2020-07)
Magnetotactic bacteria are aquatic microorganisms with the ability to biomineralise membrane-enclosed magnetic nanoparticles, called magnetosomes. These magnetosomes are arranged into a chain that behaves as a magnetic ...
Modifying the magnetic response of magnetotactic bacteria: incorporation of Gd and Tb ions into the magnetosome structure
(Royal Society of Chemistry, 2022-06)
Magnetotactic bacteria Magnetospirillum gryphiswaldense MSR-1 biosynthesise chains of cube-octahedral magnetosomes, which are 40 nm magnetite high quality (Fe3O4) nanoparticles. The magnetic properties of these crystalline ...
Magnetotactic bacteria for cancer therapy
(American Institute of Physics, 2020-08-21)
Magnetotactic bacteria (MTB) are aquatic microorganisms that are able to biomineralize membrane-enclosed magnetic nanoparticles called magnetosomes. Inside the MTB, magnetosomes are arranged in a chain that allows MTB to ...
Unlocking the Potential of Magnetotactic Bacteria as Magnetic Hyperthermia Agents
(Wiley, 2019-10)
Magnetotactic bacteria are aquatic microorganisms that internally biomineralize chains of magnetic nanoparticles (called magnetosomes) and use them as a compass. Here it is shown that magnetotactic bacteria of the strain ...
