Abstract

Magnetite is the most abundant magnetic iron mineral on the Earth’s surface. Its formation in natural ecosystems is mainly due to microbial activity. Microbially synthesized magnetite, commonly called “biogenic magnetite,” has many beneficial properties for a wide range of environmental and commercial applications. Its high surface reactivity facilitates interactions with (in)organic pollutants in anthropic and natural ecosystems, as well as with reagents in industrial catalysis. Due to its magnetic properties and good biocompatibility, biogenic magnetite is also well suited for biomedical applications such as cancer treatment or drug delivery. Biomineralization of magnetite offers an inexpensive and sustainable method for the production of this highly functional material. Moreover, this biomineralization process results in a biomolecule coating of the magnetite, making it highly amenable to further functionalization. This chapter reviews the application of biogenic magnetite across environmental, medical, and industrial settings. Existing challenges and future opportunities in these applications are also discussed.

生物磁性纳米颗粒的环境、生物医学和工业应用

磁铁矿是地球表面最丰富的磁性铁矿物。它在自然生态系统中的形成主要是由于微生物的活动。微生物合成的磁铁矿，通常被称为“生物磁铁矿”，具有广泛的环境和商业应用的许多有益特性。它的高表面反应性有助于与人类和自然生态系统中的有机污染物以及工业催化中的试剂相互作用。由于其磁性和良好的生物相容性，生物源磁铁矿也非常适合生物医学应用，如癌症治疗或药物输送。磁铁矿的生物矿化为这种高功能材料的生产提供了一种廉价和可持续的方法。此外，这种生物矿化过程导致磁铁矿的生物分子涂层，使其高度适合进一步功能化。本章回顾了生物磁铁矿在环境、医疗和工业环境中的应用。讨论了这些应用中存在的挑战和未来的机遇。
