Tuning structures : Stimulus‐responsive peptide self‐assembly requires a balance of conformational change and structural continuity of stable β sheets. In an amphiphilic bipyridine–tripeptide model, temperature, and ultrasound switch a reversible morphological transformation between vesicles and nanofibers (see picture) through the synergistic effects of terminal β‐sheet‐forming peptides, flexible linkers, and rotatable bipyridine groups.
