Introduction Supramolecular hydrogels based on the self-assembly of low-molecular-weight gelators (LMWGs) are versatile soft materials with wide-ranging applications.[1] One area of particular interest is their use in tissue engineering, where their resemblance to extracellular matrix means some of them support and direct cell growth.[2, 3] LMWG hydrogels can offer advantages over more commonly used polymer hydrogel scaffolds,[4] such as their molecular-scale tunability, reversibility, and...
