Abstract

Magnetotactic bacteria (MTB) are morphologically, physiologically, and phylogenetically diverse group (ecophysiological group) of microorganisms that are characterized by the movement along geomagnetic field lines in a process called magnetotaxis. MTB has been known to inhabit aquatic sediments (marine, estuarine, and freshwater), habitats, and rarely in the soil where vertical chemical concentration gradient exists. The cellular magnetism is usually seen due to lipid bound intracellular magnetic nanoparticles produced in MTB termed as magnetosomes. Magnetosome biosynthesis is a complex process that involves three main steps (i) invagination of cytoplasmic membrane, (ii) uptake of iron, and (iii) nucleation and maturation of magnetite crystals. Magnetosomes have a narrow size distribution when they are grown under optimal conditions and are considered to have several advantages to use for biomedical applications compared to synthetic nanoparticles. Experimental studies were conducted to compare magnetosome and synthetic magnetic nanoparticle acoustic properties, heat effects, physicochemical properties, magnetic properties, and cytotoxicity. The magnetosome’s high heating efficiency made it an effective alternative for the development of magnetic hyperthermia therapy. Another benefit of bacterial magnetosomes is their high purity levels. The biologically controlled mineralization was supposed to ensure high purity and perfect magnetosome crystal lattice, whereas the synthetic nanoparticles synthesized by the method of coprecipitation are often impure and have structural defects. In this review, we are focusing on the potential applications of bacterial magnetic nanoparticles in green nanotechnology.
