Photodynamically active AIE-functionalised casein nanofibers for antibacterial wound management in epidermolysis bullosa

(MRSA). Fluorescence imaging confirmed enhanced ROS production at the material surface. Importantly, cytocompatibility assays using keratinocytes and fibroblasts demonstrated good cytocompatibility, highlighting suitability for potential wound-contact applications. Overall, this work presents a biocompatible, photodynamically active dressing platform that integrates natural polymers with advanced AIE technology, offering a promising strategy for infection control in fragile skin conditions such as EB.
