The treatment and management of diabetic foot ulcers is a challenging issue, and this study developed a transparent monitoring system utilizing a conductive hydrogel patch to visually monitor wound-healing status and promote the healing of DFUs through various mechanisms, improving treatment efficacy.
The treatment and management of diabetic foot ulcers (DFUs) is a pretty intractable problem for clinical nursing. Urgently, the Black Box status of the healing process prevents surgeons from providing timely analysis for more effective diagnosis and therapy of the wound. Herein, we designed a transparent monitoring system to treat and manage the DFUs with blood oozing and hard-healing, which resolved the problem of blind management for the other conductive patches. This system was prepared from a conductive hydrogel patch with ultra-high transparence (up to 93.6%), adhesiveness and hemostasis, which is engineered by assembling in situ formed poly(tannic acid) (PTA)-doped polypyrrole (PPy) nanofibrils in the poly(acrylamide-acrylated adenine) (P(AM-Aa)) polymer networks. Significantly, the high transparent conductive hydrogel patch can monitor the wound-healing status visually and effectively promote the healing of DFUs by accelerating hemostasis, improving communication between cells, preventing wound infection, facilitating collagen deposition, and promoting angiogenesis. In addition, the versatile hydrogel patch could realize indirect blood glucose monitoring by detecting the glucose levels on wounds, and further sense the movements with different magnitudes of human body timely. This research may provide a novel strategy in the design of chronic wound dressings for monitoring and treating the wounds synergistically.
