In summary, this study illustrates EISA as a versatile approach for generating supramolecular hydrogels[46] from several related and cell compatible stereoisomers of pentapeptide precursors,[47] thus providing insights to create smart biomaterials with tailored properties. The difference of the morphologies of the nanofibers imply the interaction of ALP, as a protein, with the hydrogelators, which agrees with the reported interactions between proteins and low molecular weight hydrogelators[48,49], Although all the four precursors/hydrogelators are cell compatible, the origin of their cell compatibility is different, thus highlighting the versatility of EISA and the important of molecular design. Although this study focuses on pentapeptides, the knowledge obtained here is useful for designing supramolecular hydrogels from longer peptides[50-54]. In the future, replacing Nap-FF with another assembling motif, or using the D-amino acid sequence with another cleavable functional group will yield Accepted Manuscript more EISA generated supramolecular hydrogels for more broad applications, including cancer cytotoxicity or tissue engineering.
