Characterizations of polypeptide assembled hydrogel. (a) TEM image and the photographic image of the Pep self-assembled hydrogel. (b) The freeze cracking SEM image of the hydrogel. (c) (d) The G′ and G″ of the hydrogel under time scan mode and shear mode of rheological measurement, respectively. (e) The viscosity of the hydrogel under the shear mode of rheological measurement. (f) Size distribution of the Pep self-assemblies before and after shear-thinning. (g) Conformational changes in simulation box of Pep with ALA after 200 ns simulation. (h) The dynamics of RMSD within 200 ns simulation. (i) The number of hydrogen bonds between Pep and ALA during 200 ns simulation. (j) The bonding energy between peptides, solution and ALA.
