Enzyme responsive antimicrobial hyaluronan-nanocellulose hybrid wound dressings for the treatment of infected wounds

, SOAP-loaded dressings showed potent activity against clinical wound pathogens while remaining compatible with human primary dermal fibroblasts and keratinocytes. In a contaminated porcine wound model, the dressings significantly reduced bacterial load while accelerating wound re-epithelialization and epithelial maturation compared to the controls. By integrating a dual-function hydrogel that promotes healing and provides on-demand antimicrobial activity, critical limitations in the use of AMPs in wound care can be addressed, providing new possibilities to treat infected wounds.
