Platelet-rich plasma can promote the healing of chronic wound,but in clinical application,the traditional adminis-tration method cannot achieve a stable and continuous effective treatment concentration,leading to an uncertain treatment outcome.This article reviews the research on coaxial electrospinning combined with platelet-rich plasma and explores the application prospect of the new biological dressing of coaxial electrospinning combined with platelet-rich plasma in the treatment of chronic wound,in order to provide new ideas for wound treatment.
