Frontiers of Environmental Science & Engineering, 2023 Abstract Magnetotactic bacteria reside in sediments and stratified water columns. They are named after their ability to synthesize internal magnetic particles that allow them to align and swim along the Earth’s magnetic field lines. Here, we show that two magnetotactic species, Magnetospirillum magneticum strain AMB-1 and Magnetospirillum ...

Incorporation of Tb and Gd improves the diagnostic functionality of magnetotactic bacteria
Materials Today Bio, 2023 Magnetotactic bacteria are envisaged as potential theranostic agents. Their internal magnetic compass, chemical environment specificity and natural motility enable these microorganisms to behave as nanorobots, as they can be tracked and guided towards ...

Magnetosome Expression of Functional Camelid Antibody Fragments (Nanobodies) in Magnetospirillum gryphiswaldense [PDF]
Applied and Environmental Microbiology, 2011 ABSTRACT Numerous applications of conventional and biogenic magnetic nanoparticles (MNPs), such as in diagnostics, immunomagnetic separations, and magnetic cell labeling, require the immobilization of antibodies. This is usually accomplished by chemical conjugation, which, however, has several disadvantages, such as poor ...

Characterization of magnetic nanoparticles from Magnetospirillum Gryphiswaldense as potential theranostics tools [PDF]
Contrast Media & Molecular Imaging, 2015 We investigated the theranostic properties of magnetosomes (MNs) extracted from magnetotactic bacteria, promising for nanomedicine applications. Besides a physico‐chemical characterization, their potentiality as mediators for magnetic fluid hyperthermia and contrast agents for magnetic resonance imaging, both in vitro and in vivo, are here singled out.

The biomineralization of magnetosomes in Magnetospirillum gryphiswaldense
International Microbiology, 2002 Magnetotactic bacteria (MTB) are major constituents of natural microbial communities in sediments and chemically stratified water columns. The ability of MTB to migrate along magnetic field lines is based on specific intracellular structures, the magnetosomes, which, in most MTB, are nanometer-sized, membrane-bound magnetic particles consisting of the ...
