Kinetically Frozen Rheology of Agar-agar Hydrogels Upon a Change of Anions in the Hofmeister Series.

ABSTRACT: Hydrogels are materials in which water is present as the major component in a network of macromolecules, inorganic colloids or low molecular weight organogelators. To tune their viscoelastic properties, they can be crosslinked, making use of their chemical moieties, but most often with cytotoxicity issues. Another approach consists in modifying the intermolecular interactions of the gelator or its interactions with water. In this framework, playing with the nature of the used electrolyte becomes a popular approach. Even if many reports describe the influence of anions or cations in the Hofmeister series on the mechanical properties of hydrogels, very few investigate the possibility of modifying those properties in a reversible manner between two states characteristic of each electrolyte.
