Abstract：Amyloid fibrils are highly organized protein or peptide aggregates, often characterized by a distinctive supramolecular cross-β-sheet structure. The formation and accumulation of these structures have been traditionally associated with neural or systemic human diseases, such as Alzheimer's disease, Parkinson's disease, type-2 diabetes, or amyotrophic lateral sclerosis (Wei et al., 2017; Wittung-Stafshede, 2023). However, evidence exists that the amyloid fold is also exploited by nature to perform several functional, nonpathogenic roles across all kingdoms of life. For example, amyloids contribute to biofilm formation in bacteria (Peña-Díaz et al., 2024) or are involved in the regulation of transcription and alternative splicing in humans. As a general trend, amyloids display highly rigid structures with high chemical and mechanical stability, which makes them ideal scaffolds for the design of novel nanostructured materials.
