Direct Observation of Time‐Resolved Polymorphic States in the Self‐Assembly of End‐Capped Heptapeptides

Fibrillation processes in peptides: Structural states in the time-dependent self-assembly of an amyloid heptapeptide were resolved by single-molecule atomic force microscopy. Statistical analysis of the structures and their topological details revealed a continuous evolution of the polymorphs over time from the initial small spherical micelles into protofilaments, helical ribbons, and finally nanotube-like structures (see picture).
