Development of functional nano-particles using biomineralization process in magnetic bacteria

我们开发了一种利用趋磁细菌的磁铁矿生物矿化蛋白合成功能性纳米颗粒的方法。利用蛋白质调控纳米颗粒的形状、大小和磁性。Bar结构域蛋白用于控制纳米晶体合成的空间，铁转运蛋白用于建立脂质体中的顺序晶体形成过程。本研究开发的纳米粒子将作为纳米材料应用于生物技术和磁记录领域。

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.
