Microenvironment-adaptive cationic guar gum hydrogel co-loaded with BPNS@MnO2 nanozyme and berberine for infected burn wound healing.
Infected burn wounds are characterized by bacterial invasion, oxidative stress, and persistent inflammation, which severely impair tissue regeneration. Herein, we report a crosslinker-free, hydrogen-bonded cationic guar gum hydrogel (CBBM) co-loaded with berberine (BBR) and MnO2-coated black phosphorus nanosheets (BPNS...
