“…Wound dressings have long been used to aid healing by providing a physical barrier against infection, maintaining a moist environment, and absorbing exudates around the wound. , An ideal wound dressing must meet the following criteria: (i) adsorb and remove the exudate and toxins, (ii) keep high moisture at the dressing-wound interface, (iii) allow gaseous exchange, (iv) provide thermal insulation, (v) avoid secondary infection, and (vi) have no cytotoxicity. However, more demands on an ideal wound dressing have been raised recently, such as being comfortable, durable, nonirritant, nonadherent and effortlessly removed without trauma, no delayed step in the wound healing process, releasing mediators and antimicrobials for wound healing, and so on. , However, most existing wound dressings only bear single biological activity, which limits the multiple promoting effects on wound healing. Therefore, it is in high demand to develop a multifunctional bioactive and smart wound dressing that can accelerate the wound closure, promote the wound healing, and reduce the formation of a scar.…”
