Applications of Magnetotactic Bacteria, Magnetosomes and Magnetosome Crystals in Biotechnology and Nanotechnology: Mini-Review [PDF]
Molecules, 2018 Magnetotactic bacteria (MTB) biomineralize magnetosomes, which are defined as intracellular nanocrystals of the magnetic minerals magnetite (Fe3O4) or greigite (Fe3S4) enveloped by a phospholipid bilayer membrane. The synthesis of magnetosomes is controlled by a specific set of genes that encode proteins, some of which are exclusively found in the ...

Magnetotactic bacteria, magnetosomes and their application
Microbiological Research, 2012 Magnetotactic bacteria (MTB) are a diverse group of microorganisms with the ability to orient and migrate along geomagnetic field lines. This unique feat is based on specific intracellular organelles, the magnetosomes, which, in most MTB, comprise nanometer-sized, membrane bound crystals of magnetic iron minerals and organized into chains via a ...

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Deep‐sea rare earth elements and yttrium (REY)‐rich sediments have attracted considerable attention since their discovery in 2011. However, the environmental factors controlling REY enrichment remain poorly understood, largely because paleoceanographic proxies are absent in pelagic clays.

Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms
Advanced Materials, Volume 38, Issue 9, 12 February 2026.This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.

Directed Navigation of Magnetotactic Bacteria via Magnetotaxis in a 3D Vasculature‐On‐A‐Chip
Advanced Materials Technologies, Volume 11, Issue 4, 19 February 2026.A perfusable vascular network is developed to investigate MTB at the single‐microorganism level. MTB is demonstrated to successfully align and navigate along the magnetic field inside the microvessels. Abstract Magnetotactic bacteria (MTB), inherently motile and self‐powered, are promising biorobotic candidates for targeted anti‐cancer drug delivery ...
