Abstract

A dispersion of a peptide amphiphile into water forms hierarchical fibril structures, leading to a supramolecular hydrogel. In contrast to polymeric hydrogels, such gel exhibit a transition between sol and gel states. Here, we report on a spatial heterogeneity during the sol-to-gel transition by a particle tracking technique. The sol obtained by disrupting the gel was heterogeneous in terms of its physical properties. The extent of heterogeneity in the sol decreased as the re-gelation proceeded.
