Multifunctional hydrogel assembled from phenylboronic acid-chitosan and Polygonati Rhizoma polysaccharide for accelerated radiation-combined wound healing.
Combined radiation-wound injury (CRWI) is difficult to heal because of persistent oxidative stress, inflammation, and impaired angiogenesis. Herein, a multifunctional pH and reactive oxygen species (ROS)-responsive hydrogel was prepared by dynamic crosslinking of Polygonati Rhizoma-derived polysaccharide fraction (PC)...
