| الوصف: |
The large amount of reactive oxygen species (ROS) produced by high glucose metabolism in diabetic patients not only induces inflammation but also damages blood vessels, finally resulting in low limb temperature, and the high glucose environment in diabetic patients also makes them susceptible to bacterial infection. Therefore, diabetic foot ulcer (DFU) usually presents as a nonhealing wound. To efficaciously prevent and treat DFU, we proposed a near-infrared (NIR) responsive microneedle (MN) patch hierarchical microparticle (HMP)-ZnO-MN-vascular endothelial growth factor and basic fibroblast growth factor (H-Z-MN-VEGF&bFGF), which could deliver drugs to the limbs painlessly, accurately, and controllably under NIR irradiation. Therein, the hair-derived HMPs exhibited the capacity of scavenging ROS, thereby preventing damage to the blood vessels. Meanwhile, zinc oxide (ZnO) nanoparticles endowed the MN patch with excellent antibacterial activity which could be further enhanced with the photothermal effect of HMPs under NIR irradiation. Moreover, vascular endothelial growth factor and basic fibroblast growth factor could promote the angiogenesis. A series of experiments proved that the MN patch exhibited broad-spectrum antibacterial and anti-inflammatory capacities. In vivo , it obviously increased the temperature of fingertips in diabetic rats as well as promoted collagen deposition and angiogenesis during wound healing. In conclusion, this therapeutic platform provides a promising method for the prevention and treatment of DFU. |
