Reversibly crosslinkable polymeric networks, including reversibly crosslinkable hydrogel networks are provided. Also provided are methods of making the polymeric networks and methods of using the hydrogel networks in tissue engineering applications. The reversibly crosslinkable polymeric networks are composed of polymer chains that are covalently crosslinked by azobenzene boronic ester bonds that can be reversibly formed and broken by exposing the polymeric networks to different wavelengths of light.

Photocontrolled dynamic covalent linkers for polymer networks

The present invention generally relates to compositions and methods for forming droplets and/or emulsions. In some embodiments, the compositions and methods comprise two or more components miscible at a first temperature and immiscible at a second temperature, dispersed in an outer phase.

Compositions and methods for forming emulsions

The present invention generally relates to colloids and methods for changing the arrangement of droplet phases. In some embodiments, the colloids and methods comprise a plurality of droplets comprising two or more components, such that the two or more components can change arrangement of the components in the presence of an external stimulus. In some embodiments, the change in component arrangement is reversible. In certain embodiments, the change in component arrangement forms Janus droplets.
