Distinctive feature : Two‐dimensional ultraviolet (2DUV) spectroscopy can be utilized to identify protein sequences capable of forming fibrils. The Rosetta free energy of proteins, which is a good indicator of fibrillation propensity, has distinct 2DUV signatures. An additional positive diagonal peak at 54 000–58 000 cm −1 in chiral xxxy spectra serves as a indicator of the ability of protein sequences to form amyloid‐like fibrils.
