An advanced wound care dressing against laser patterned mesh foam dressing OLED patch

Effective management and treatment of wounds remain one of the primary objectives in clinical medicine. In conjunction with technological advancements, it has become possible to provide safe and effective treatments that minimize scarring and side effects by integrating various dressings, pharmaceuticals, and optical therapies. In this study, we aimed to integrate wound dressings with optical therapy to achieve more efficient wound management. A facile mesh-patterned foam substrate, fabricated via laser patterning, was integrated with Organic Light-Emitting Diodes (OLEDs). This mesh foam enabled the implementation of MFOLEDs by overcoming the conventional limitations of foam dressings, which were previously considered incompatible with OLEDs due to their low optical transmittance. Using these flexible and wearable Mesh Foam OLEDs (MFOLEDs), we successfully promoted HaCaT cell proliferation by over 70 percent at an optical output of 10 mW cm^-2. Our findings suggest that MFOLEDs demonstrate great promise as an advanced wound care dressing for the effective treatment of various open wounds.
