Exosome‐mimetic vesicle‐encapsulated multi‐responsive antibacterial hydrogel core‐shell microneedle patch promotes scarless healing of infected wounds
Clinical stage‐adaptive treatment strategies for infected wounds face temporal challenges due to the varying demands for antibacterial, anti‐inflammatory and anti‐scarring effects during different stages of healing. In this study, a core‐shell microneedle (MN) patch with spatiotemporally programmed release was deve...
