Engineering Light-Activated Peptide Assemblies

The design of photoresponsive supramolecular peptides hinges on incorporating photo-switchable units into peptide sequences or structures. A common strategy involves the use of azobenzene moieties, which undergo reversible *cis-trans* isomerization upon exposure to specific wavelengths of lightPeptide-Based Supramolecular Systems Chemistry. This isomerization can trigger or inhibit the self-assembly of peptide building blocks into larger, ordered supramolecular structures, such as fibers, nanotubes, or hydrogels. For instance, photocaged pro-assembling peptides can be designed to remain inactive until illuminated, at which point they initiate supramolecular assembly inside complex cellular environmentsDynamic Control with Photoresponsive Peptide Hydrogels. Similarly, photoresponsive peptide fibers can be developed by integrating azobenzene into their structure, allowing for light-induced changes in their morphology and properties.
