Photo-expanding Spiropyran Hydrogels
yle>
2021-037
Short Description
Sulfonate-based, water-soluble spiropyran photoswitches can be covalently incorporated into hydrogel networks to trigger light-driven volumetric expansion, with reversible contraction under dark conditions. The technology enables photoresponsive hydrogels and soft materials with tunable actuation behavior using light,...
