在实际应用中使用生物纳米结构需要精确控制生物分子自组装以及扩大这些材料生产规模的能力(1)。一个重大挑战是控制宏观表面上大而均匀的生物纳米结构阵列的形成(2-4)。此前，生物纳米结构的形成基于本体溶液中异质群体的自发生长(1)。在这里，我们展示了使用气相沉积方法自组装大型芳香肽纳米管阵列。这种方法可以通过仔细控制气相结构单元的供应来微调纳米管的长度和密度。此外，我们还表明，纳米管阵列可用于开发用于储能应用的高表面积电极、高疏水性自清洁表面和微流控芯片。
The use of bionanostructures in real-world applications will require precise control over biomolecular self-assembly and the ability to scale up production of these materials(1). A significant challenge is to control the formation of large, homogeneous arrays of bionanostructures on macroscopic surfaces(2-4). Previously, bionanostructure formation has been based on the spontaneous growth of heterogenic populations in bulk solution(1). Here, we demonstrate the self-assembly of large arrays of aromatic peptide nanotubes using vapour deposition methods. This approach allows the length and density of the nanotubes to be fine-tuned by carefully controlling the supply of the building blocks from the gas phase. Furthermore, we show that the nanotube arrays can be used to develop high-surface-area electrodes for energy storage applications, highly hydrophobic self-cleaning surfaces and microfluidic chips.
