Temporary cross-linking can turn biomolecular building blocks into dynamic, water-compatible networks. In article number e26058, Colin D. Kinz-Thompson and co-workers show the repurposing of a protein's binding interaction to create bifunctional cross-linkers and make such networks from streptavidin. These networks exhibit complex architectures subject to both kinetic and thermodynamic control and can even be controlled by the environmental pH and magnets.
Dai et al. (Mon,) studied this question.
