U.S. and Australian researchers develop biodegradable and smart wound patches for better chronic wound healing.

Researchers at the University of Mississippi are developing 3D-printed, biodegradable patches for chronic wounds using natural materials like chitosan and plant-based antimicrobials to promote healing and prevent infection without causing antibiotic resistance. The custom-fit patches dissolve in the body, avoiding removal and irritation, and could benefit remote or military settings. Separately, Australian researchers created a smart wound dressing with carbon dots in a hydrogel that detects infection via pH changes, showing color shifts visible on smartphones, and automatically releases nanozymes to fight inflammation. The patch can also be manually activated. Both technologies aim to improve chronic wound care, enable early intervention, and integrate with digital health systems, though further testing and regulatory approval are needed before clinical use.
