title: From Soft Self-Healing Gels to Stiff Films in Suckerin-Based Materials Through Modulation of Crosslink Density and β-Sheet Content.
abstract: Suckerins are block-copolymer-like structural proteins constituting the building blocks of the strong squid sucker-ring teeth. Here, recombinant suckerin-19 is processed into biomaterials spanning a wide range of elasticity, from very soft hydrogels to stiff films with elastic modulus in the gigapascal range. The elasticity is controlled by the interplay between the β-sheet content and induced di-tyrosine crosslinking.
