Abstract

In present work the magnetic properties of biomineral ferrihydrite nanoparticles (biomass), produced by Klebsiella oxytoca strain and the nanoparticles obtained by drying the sol (sol), made on the basis of biomineral ferrihydrite nanoparticles have been studied. Ferrihydrite nanoparticles are formed on the surface of the bacterial cell..

Keywords

Magnetic nanoparticles, Biosynthesis, Ferrihydrite, superparamagnetics.
