 This research has developed a new type of wound dressing that uses bacteriophages to treat infected wounds. Electrospinning was used to create a protective polymer shell around the bacteriophages, allowing them to be applied directly to the wound without losing any of their antimicrobial activity. This new approach has been shown to have good mechanical properties, such as a reproducible fibre diameter range and optimal fibre morphology, which makes it suitable for use on wounds. Additionally, the bacteriophages were found to retain their antimicrobial activity even after being stored at minus 20 degrees Celsius for four weeks. These results suggest that this new approach could be used to develop a safe and effective way to deliver bacteriophages to infected wounds, potentially revolutionizing the field of phage therapy.
