Diabetic wounds are characterized by the disruption and cessation of essential healing stages, which include hemostasis, inflammation, proliferation, and remodeling. However, traditional treatments for diabetic wounds concentrate on individual stages of the healing process. Herein, this study utilizes mask-mediated sequential polymerization and varied cross-linking techniques to develop dual-modular microneedles (MNs) with fast- and slow-module, exhibiting varying degradation rates tailored for the full spectrum of diabetic wound healing. First, MNs incorporating calcium ions and dopamine synergistically promote rapid hemostasis. Second, fast-module physically cross-linked MNs rapidly D-mannose/dopamine-enhanced tripolyphosphate-quaternized chitosan (mDTC) nanoparticles (NPs) loaded with microRNA-147 (miRNA-147) to manage inflammation and oxidative stress in diabetic wounds. Additionally, dopamine in these NPs enhances their internalization and safeguards miRNA-147 from oxidative stress and RNase degradation. Finally, slow-module chemically cross-linked MNs facilitate the continuous release of deferoxamine (DFO) and dopamine, accelerating angiogenesis and tissue regeneration during the proliferation and remodeling stages. Manganese/dopamine-enhanced calcium peroxide NPs within the MNs initiate a blast-like generation of oxygen bubbles, not only enhancing the delivery of miRNA-mDTC NPs and DFO but also alleviating tissue hypoxia. Consequently, dual-modular MNs are instrumental in promoting rapid and complete healing of diabetic wounds through all stages of healing.
