Tumor killing and wound healing are two complementary and influential processes during the treatment of melanoma. Herein, a two-layered microneedle platform was developed with bifunctional effect of chemo-photothermal synergistic melanoma therapy and skin regeneration. The bifunctional platform composed of embeddable curcumin nanodrugs/new Indocyanine Green/hyaluronic acid (Cur NDs/IR820/HA) microneedles and sodium alginate/gelatin/hyaluronic acid (SA/Ge/HA) supporting backing layer was prepared through a two-step casting process. With uniform incorporation of curcumin nanodrugs and IR820, the microneedles exhibited excellent photothermal performance under external near-infrared (NIR) light stimulation and tumor co-therapy ability. Once the embeddable microneedles were inserted into skin, they would rapidly dissolve and activate drug release successfully for tumor treatment. Moreover, the SA/Ge/HA supporting backing layer was left behind to cover the wound and promote the proliferation of endothelial and fibroblasts cells for enhanced skin regeneration. The two-layered microneedles platform can simultaneously eliminate the tumor and accelerate wounding healing, which may be potentially employed as a competitive strategy for the treatment of melanoma.
肿瘤杀伤和伤口愈合是黑色素瘤治疗过程中的两个互补且有影响的过程。在此,开发了一种具有化学-光热协同黑色素瘤治疗和皮肤再生双重功能的双层微针平台。该双层平台由可嵌入的姜黄素纳米药物/新吲哚菁绿/透明质酸(Cur NDs/IR820/HA)微针和海藻酸钠/明胶/透明质酸(SA/Ge/HA)支撑背衬层组成,通过两步浇铸工艺制备而成。通过均匀掺入姜黄素纳米药物和 IR820,微针在外部近红外(NIR)光刺激下表现出优异的光热性能和肿瘤协同治疗能力。一旦可嵌入的微针插入皮肤,它们将迅速溶解并成功激活药物释放以进行肿瘤治疗。此外,SA/Ge/HA 支撑背衬层会留在原处覆盖伤口,促进内皮细胞和成纤维细胞的增殖,从而增强皮肤再生。双层微针平台可以同时消除肿瘤并加速伤口愈合,这可能成为治疗黑色素瘤的一种有竞争力的策略。
