A biofluid absorbing sandwich-structured wound dressing (SWD) designed by organic-inorganic hybrid Janus membrane containing hardystonite (ZnCS, Ca2ZnSi2O7) and the application in deep burn wound healing with enhanced hair growth and angiogenesis. (The wound fluid is absorbed by the powder in the sandwich dressing, which then releases bioactive ions for stimulating the regeneration of blood vessels and hair follicles.) (a) The design and preparation of the ZnCS-SWD. (b) ZnCS-SWD promote burn wound healing and hair follicle regeneration.
