Biochemical Magnetite Formation and its Application

  • T. Hamaya

Magnetic particles have important applications in biochemistry and in medicine, for example in magnetoliposomes for cell sorting1 and for magnetic separation techniques2. Particles from magnetotactic bacteria are most suitable for such applications by virtue of their size3, but cannot be recovered in sufficient quantities for commercial purpose, because the growth of magnetotactic bacteria in culture is limited. This study was designed to gain an understanding of the mechanisms of magnetite formation in living organisms, and to synthesize magnetite particles for industrial applications.
