Magnetotactic bacteria are able to biomineralize magnetic crystals in intracellular organelles, so-called "magnetosomes." These particles exhibit species- and strain-specific size and morphology. They are of great interest for biomimetic nanotechnological and biotechnological research due to their fine-tuned magnetic properties and because they challenge our understanding of the classical principles of crystallization. Magnetotactic bacteria use these highly optimized particles, which form chains within the bacterial cells, as a magnetic field actuator, enabling them to navigate. In this chapter, we discuss the current biological and chemical knowledge of magnetite biomineralization in these bacteria. We highlight the extraordinary properties of magnetosomes and some resulting potential applications.
趋磁细菌能够在细胞内细胞器（即所谓的“磁小体”）中生物矿化形成磁性晶体。这些颗粒呈现出物种和菌株特异性的大小和形态。由于其经过精细调节的磁性特性，以及它们对我们传统结晶原理理解的挑战，它们在仿生纳米技术和生物技术研究中备受关注。趋磁细菌利用这些高度优化的颗粒（它们在细菌细胞内形成链状）作为磁场驱动器，使其能够导航。在本章中，我们讨论了这些细菌中磁铁矿生物矿化的当前生物学和化学知识。我们强调了磁小体的非凡特性以及由此产生的一些潜在应用。
