Skin has an amazing capability to heal itself. However, in some severe cases, it takes too long to heal or at times it does not even heal. This results in chronic pain or even in severe scarring and infection to the patient. Thus, a team of researchers have recently developed a self-powdered bandages, which generates an electric field on the injury and impulsively reduce the healing time for the wounds. This study was conducted by the team of researchers on rats and the findings have been reported in ACS Nano.
Some of the chronic skin wounds that demands for self-powdered bandages include venous ulcers, diabetic foot ulcer, and non-healing surgical wounds. Doctors have taken several efforts and have tried several approaches to help the chronic wounds heal, which comprises dressing, bandaging, and exposure to the oxygen. However, all these attempts have showcased limited effectiveness. Earlier, researchers have observed that the electric simulation helps in healing of skin wounds. The equipment available that time were very large in size and required hospitalization of the patient.
Xudong Wang, Weibo Cai Xudong and colleagues were making efforts to develop a self-powered and flexible bandages. These bandages will help in converting the skin movements into an effective therapeutic electric field. The team of researchers developed a wearable nano-generator by overlapping the sheets of copper field, polytetrafluoroethylene, and polyethylene terephthalate. The wounds that are covered in these bandages close in a span of three days and help the patients in healing fast.
