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 ...
Enhanced mass sensitivity in novel magnetoelastic resonators geometries for advanced detection systems
(Elsevier, 2019-10-01)
Acoustic wave based sensors have a major impact in the detection of low concentration of biological and chemical agents. Magnetoelastic resonator platforms are particularly interesting due to their low cost and wireless ...
Exploring the Different Degrees of Magnetic Disorder in TbxR1−xCu2 Nanoparticle Alloys
(MDPI, 2020-10-28)
Recently, potential technological interest has been revealed for the production of magnetocaloric alloys using Rare-Earth intermetallics. In this work, three series of TbxR1−xCu2 (R ≡ Gd, La, Y) alloys have been produced ...
Tuning the Magnetic Response of Magnetospirillum magneticum by Changing the Culture Medium: A Straightforward Approach to Improve Their Hyperthermia Efficiency
(American Chemical Society, 2023)
Magnetotactic bacteria Magnetospirillum magneticum AMB-1 have been cultured using three different media: magnetic spirillum growth medium with Wolfe’s mineral solution (MSGM + W), magnetic spirillum growth medium without ...
Nanoflowers versus magnetosomes: comparison between two promising candidates for magnetic hyperthermia therapy
(IEEE Access, 2021-07-12)
[EN] Magnetic Fluid Hyperthermia mediated by iron oxide nanoparticles is one of the most
promising therapies for cancer treatment. Among the different candidates, magnetite and maghemite
nanoparticles have revealed to ...
Configuration of the magnetosome chain: a natural magnetic nanoarchitecture
(Royal Society of Chemistry, 2018)
Magnetospirillum gryphiswaldense is a microorganism with the ability to biomineralize magnetite nanoparticles, called magnetosomes, and arrange them into a chain that behaves like a magnetic compass. Rather than straight ...
