Preparation of metal–organic framework combined with Portulaca oleracea L. extract electrostatically spun nanofiber membranes delayed release wound dressing

). The antioxidant properties of the nanofiber membranes loaded with POE were further validated through the DPPH radical scavenging test. These findings highlight the potential application of the developed nanofiber membranes in wound dressings, offering controlled and sustained drug-release capabilities.
