Wound healing is a complex, variable, and time-dynamic repair process. Wounds can be classified as acute wounds or chronic wounds, effective wound management still major challenge in clinical nursing settings. The microenvironment collectively regulated by internal biomolecules, external drugs, sanitation. Traditional dressings (powders, bandages, sponges, etc.) often have poor therapeutic effects during processes because they cannot respond to the dynamic changes over long-term. Stimulus-responsive biomaterials, which are activated various factors intrinsic influences, hold great promise for precise drug delivery controlled release. Various stimulus-responsive hydrogels been developed recent years, exhibiting range of “smart” properties, such interacting with wound, sensing conditions environmental changes, responding accordingly, thereby effectively promoting healing. This review discusses latest advancements used We introduce design scheme stimulus-response detail based on local biological/biochemical peculiarities (pH, reactive oxygen species glucose, enzymes, physical microenvironments (temperature, light, ultrasound, electric fields, etc.). Furthermore, we explore several promising tissue-engineered constructs (nanofibers, scaffolds, microneedles, microspheres).
