Amyloid nanofibrils (ANFs) are supramolecular polymers originally classified as pathological markers in various human degenerative diseases. However, in recent years, ANFs have garnered greater interest and are regarded as nature-based sustainable biomaterials in environmental science, material engineering, and nanotechnology. On a laboratory scale, ANFs can be produced from food proteins via protein unfolding, misfolding, and hydrolysis. Furthermore, ANFs have specific structural characteristics such as a high aspect ratio, good rigidity, chemical stability, and a controllable sequence. These properties make them a promising functional material in water decontamination research. As a result, the fabrication and application of ANFs and their composites in water purification have recently gained considerable attention. Despite the large amount of literature in this field, there is a lack of systematic review to assess the gap in using ANFs and their composites to remove contaminants from water. This review discusses significant advancements in design techniques as well as the physicochemical properties of ANFs-based composites. We also emphasize the current progress in using ANFs-based composites to remove inorganic, organic, and biological contaminants. The interaction mechanisms between ANFs-based composites and contaminants are also highlighted. Finally, we illustrate the challenges and opportunities associated with the future preparation and application of ANFs-based composites. We anticipate that this review will shed new light on the future design and use of ANFs-based composites.
淀粉样纳米纤维（ANFs）是一种超分子聚合物，最初被归类为各种人类退行性疾病的病理标志物。然而，近年来，ANFs引起了更大的关注，并在环境科学、材料工程和纳米技术领域被视为基于天然的可持续生物材料。在实验室规模上，ANFs可以通过食品蛋白质的展开、错误折叠和水解来制备。此外，ANFs具有高长径比、良好的刚性、化学稳定性和可控序列等特定结构特征。这些特性使其成为水净化研究中一种有前途的功能材料。因此，ANFs及其复合材料在水净化中的制备和应用最近受到了相当大的关注。尽管该领域有大量文献，但缺乏系统的综述来评估使用ANFs及其复合材料去除水中污染物方面的差距。本综述讨论了设计技术的重大进展以及基于ANFs的复合材料的物理化学性质。我们还强调了使用基于ANFs的复合材料去除无机、有机和生物污染物方面的当前进展。基于ANFs的复合材料与污染物之间的相互作用机制也得到了突出。最后，我们阐述了基于ANFs的复合材料未来制备和应用所面临的挑战和机遇。我们预计本综述将为基于ANFs的复合材料的未来设计和使用提供新的思路。
