The fabrication of inorganic nanomaterials is important for a wide range of disciplines. While many purely inorganic synthetic routes have enabled a manifold of nanostructures under well-controlled conditions, organisms have the ability to synthesize structures under ambient conditions. For example, magnetotactic bacteria, can synthesize tiny 'compass needles' of magnetite (FeO). Here, we demonstrate the bio-inspired synthesis of extended, self-supporting, nanometer-thin sheets of iron oxide at the water-air interface through self-assembly using small histidine-rich peptides.
无机纳米材料的制备对众多学科都很重要。虽然许多纯无机合成路线能在严格控制的条件下制备出多种纳米结构,但生物体有能力在环境条件下合成结构。例如,趋磁细菌能合成微小的磁铁矿(FeO)“指南针针”。在此,我们展示了通过使用富含组氨酸的小肽进行自组装,在水 - 空气界面仿生合成延伸的、自支撑的纳米级薄氧化铁片。
