a Potential energy surface showing the formation of peptide oligomers (strings of beads). The depth of the wells represents the relative stability of the self-assembling peptides formed. b Schematic representation of the dynamic peptide library approach to discover supramolecular materials, which involves (mixtures of) dipeptides (dyads) as chemical inputs, dynamic exchange of peptide sequences initiated by exchange and selection through enzymatic condensation, hydrolysis and transacylation, with the most-stable self-assembling structure eventually emerging (peptide nanostructure).
