| Research Abstract |
We developed a method for synthesis of functional nano-particles using proteins involved in magnetite biomineralization of magnetotactic bacteria. Shape, size and magnetic property of nano-particles were regulated by using proteins responsible for magnetite crystal formation. Bar domain protein was used to control space for nano-crystal synthesis, and iron transporter protein was used for establishment of sequential crystal formation process in liposomes. The nano-particles developed in this study will be used as nano-materials in the fields of biotechnology and magnetic recordings.
