Diabetic　ulcer　is　one　of　the　most　serious　complications　of　diabetes　mellitus.　It　has　the　characteristics　of　long　healing　cycle,　difficulty　in　cure　and　high　recurrence　rate.　Dressing　as　an　important　part　of　the　treatment　of　diabetic　ulcers　cannot　be　ignored.　Ideal　wound　dressings　should　have　characteristics　of　hemostasis,　antibacterial　property　and　high　biocompatibility,　while　traditional　dressings　are　far　from　meeting　the　needs　of　diabetic　wounds.　With　the　development　of　nanotechnology,　nanofiber　dressings　prepared　by　electrospinning　technology　have　made　some　progress　in　the　treatment　of　diabetic　ulcers.　Therefore,　based　on　the　understanding　of　the　refractory　mechanism　of　diabetic　ulcers,　the　matrix　materials,　loading　materials　and　research　status　of　electrospun　nanofiber　dressings　were　reviewed,　so　as　to　provide　reference　for　further　research.　©　2023,　China　Biotechnology　Press.　All　rights　reserved.
