Learning from the stabilization of protein structures, we combine aromatic-aromatic and electrostatic interactions to tailor the elasticity of supramolecular hydrogels. Specifically, calcium ions allow interfiber cross-links among the supramolecular nanofibers of small peptides that consist of multiple carboxylic acid and aromatic groups. A small change in the concentration of calcium increases the elasticity of hydrogels over several orders of magnitude. This simple approach not only demonstrat ...[more]
