Plasma-Depolymerised Chitosan for Wound Healing This cover illustrates plasma bubble–driven depolymerisation of chitosan into low-molecular-weight fragments with enhanced antibacterial activity and wound-healing potential. The study reveals that plasma-emitted UV radiation weakens glycosidic bonds within the chitosan backbone, making them more susceptible to attack by plasma-generated ROS. This synergistic mechanism enables controlled polymer breakdown and generates bioactive chitosan derivatives with improved therapeutic performance.
