(MDPI, 2018-03)
Hydrogels are biomimetic materials widely used in the area of biomedical engineering and biosensing. Ferrogels (FG) are magnetic composites capable of functioning as magnetic field sensitive transformers and field assisted ...
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 ...
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 ...
Probing the Stability and Magnetic Properties of Magnetosome Chains in Freeze-Dried Magnetotactic Bacteria
(Royal Society Of Chemistry, 2020-03-01)
Magnetospirillum gryphiswaldense biosynthesize high-quality magnetite nanoparticles, called magnetosomes, and arrange them into a chain that behaves like a magnetic compass. Here we perform magnetometry and polarized ...
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 ...
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 ...
A Milestone in the Chemical Synthesis of Fe3O4 Nanoparticles: Unreported Bulklike Properties Lead to a Remarkable Magnetic Hyperthermia
(ACS, 2021-11-10)
Among iron oxide phases, magnetite (Fe3O4) is
often the preferred one for nanotechnological and biomedical
applications because of its high saturation magnetization and low
toxicity. Although there are several synthetic ...
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 ...
