Fig. 3. Experimental investigations on the self-assembly behavior of 165 synthetic tetrapeptides.

Fig. 3

a TEM images of 6 representative hydrogels of synthetic tetrapeptides, respectively. Inserts: optical images of the corresponding hydrogel (pH between 7.0 to 7.5). MD simulation results (1250 ns) and APHC ranking were shown in the right column. b Dynamic frequency sweep of tetrapeptide hydrogels at the strain value of 0.5%. c FTIR spectra in the amide I region of tetrapeptide hydrogels. d TEM images of 6 representative non-hydrogels of tetrapeptide Insets: optical images of corresponding solution/suspension (pH = 7.5). MD simulation results (1250 ns) and APHC ranking were shown in the right column. e Statistics and classification of morphologies obtained by TEM for hydrogel-forming tetrapeptides (100 peptides). f Statistics and classification of morphologies obtained by TEM for non-hydrogel-forming tetrapeptides (65 peptides).
