Schematical illustration of the greigite-containing magnetosome and the chemical synthesized magnetosome-like GMNCs.
Natural Greigite-containing magnetosomes with lipid bilayer are produced by the sulfate-reducing magnetic bacteria, while the synthesis of magnetosome-like GMNCs with similar protecting membrane is carried out in mild chemical conditions with the bound of β- CD and PEG molecules.
