Top-down curing to construct self-retaining and moisture-pumping double-layered dressing with enhanced antibacterial, hemostatic, and wound healing performances.

Continuous microenvironment modulation is an ongoing challenge in wound dressing, which includes excessive exudate absorption, oxygen delivery, bacterial inhibition and angiogenesis. Herein, we developed an construction strategy to fabricate a self-retaining double-layered wound dressing, where the top layer precursor was composed of Ca-containing polyvinyl butyral (PVB) solution dispersed with hydroxypropyl methylcellulose (HPMC) particles, and the bottom one consisted of sodium alginate (Alg) solution blended with Ag-doped mesoporous bioactive glass powders (Ag-MBG). When in use, both precursors were simultaneously squeezed out from the twin nozzles connected to the individual chambers of a twin-chambered syringe, whereby Ca in the top layer rapidly migrated downwards to crosslink Alg in the bottom layer, leading to the formation of an Alg/Ag-MBG (AA) functional hydrogel for filling an irregular wound.
