TLDR The microneedle patch helps heal infected wounds quickly and without scars.
The study introduces a novel antimicrobial microneedle patch (ApoEVs-AT@MNP) designed for the controlled release of adipose tissue-derived apoptotic vesicles to treat infected wounds. This patch not only inhibits bacterial growth but also significantly enhances scarless wound healing and promotes the rapid formation of mature hair follicles, observed as early as 8 days post-implantation. The microneedle patch is noted for its mechanical strength, ability to penetrate the skin, and safe degradation within the body, making it a promising, painless, and non-invasive treatment option for infected wounds.
