Epidermal growth factor is an excellent drug for promoting wound healing; however, its conventional administration strategies are associated with pharmacodynamic challenges, such as low transdermal permeability, reduction, and receptor desensitization. Here, we develop a microneedle-based self-powered transcutaneous electrical stimulation system (mn-STESS) by integrating sliding free-standing triboelectric nanogenerator microneedle patch to achieve improved epidermal pharmacodynamics. We show that the mn-STESS facilitates penetration utilization using microneedles pierce stratum corneum. More importantly, find it converts mechanical energy of finger into electricity mediates through microneedles. demonstrate applied acts "adjuvant" suppresses reduction glutathione upregulates expression in keratinocyte cells, successfully compensating Collectively, this work highlights promise adjuvants improving pharmacodynamics, creating combinatorial therapeutic traditional drugs.

Abstract Diabetic wounds are difficult to heal, and the key wound healing is exudate management effective disinfection. Inspired by asymmetric wettability of Janus‐structured lotus leaves, herein study has presented design a biomimetic Janus membrane that integrates unidirectional biofluid drainage photothermal‐enhanced evaporation/sterilization capabilities for accelerating diabetic healing. This prepared electrospinning polyacrylonitrile (PAN) nanofiber containing polydopamine (PDA) on surface polypropylene (PP) nonwoven membrane. Such PP/PAN x%PDA enables antigravity “pumping” water from hydrophobic PP layer hydrophilic PAN within 22 s through contact points interface. The incorporation 30 wt% PDA in imparts high photoabsorption photothermal responsiveness, facilitating continuous volatilization exudate, achieving twice displacement water, causing irreversible damage bacteria. As result, it effectively alleviates inflammation cellular fibrosis while promoting collagen deposition due its structure antibacterial properties. Impressively, such achieves an impressive closure rate 96.7% wounds, better than (59.8%) conventional bandages. Therefore, this offers promising alternative chronic wounds.

Diabetic wound healing remains as a serious challenge for medical circles that required continuous monitoring and effective management. Herein, the glucose oxidase/carbon dots@copper-metal–organic framework-based nanofibers (GOx/CDs@MOF NFs) were proposed multifunctional dressing, aiming to visually monitor pH inhibit bacterial infection. In diabetic microenvironment, GOx/CDs@MOF NFs could convert endogenous into hydroxyl radial (•OH) through cascade catalytic reaction. vivo vitro experimental results confirmed efficiently kill bacteria promote healing. Additionally, CDs fluorescent indicator endowed with sensitive reversible sensing behavior pH, these visual images also be captured by smartphones transformed RGB color mode (red, green, blue) values, allowing onsite evaluation of status. This dressing provides smart solution management takes an immeasurable step toward development next generation digitally visualized dressings.
