Decoupling Dynamics and Crosslink Stability in Supramolecular Hydrogels Using Associative Exchange
Advanced Materials, EarlyView.How does reorganization impact the stability of supramolecular hydrogels? In contrast to dissociative crosslink exchange, implementing associative exchange in macroscale DNA hydrogels enables decoupling of reorganization dynamics from thermal and mechanical stability.
