Reactive Oxygen Species Suppressive Kraft Lignin-Gelatin Antioxidant Hydrogels for Chronic Wound Repair

Front Cover: Chronic wound generates high levels of reactive oxygen species (ROS), which inhibits normal wound healing process. In article number 2200234, Justin J. Chung and co-workers fabricate ROS suppressive and antioxidant hydrogel by chemically cross-linking kraft lignin with gelatin. The flexible kraft lignin-gelatin hydrogel is able to suppress ROS, and exhibit antibacterial activity.
