Researchers have developed a wearable device that uses light to kill bacteria in chronic wounds. The ACEL mPDT device is powered by the wearer’s movements and designed to be safe and effective for treating wounds infected with MRSA.
The device is made of a flexible material that conforms to the body. It contains a hydrogel electrode loaded with a photosensitizer molecule. When light is shone on the photosensitizer, it produces reactive oxygen species (ROS), which are toxic to bacteria.
The ACEL mPDT device is powered by a triboelectric nanogenerator (TENG), a device that converts mechanical energy into electrical energy. In the device, the TENG harvests energy from the wearer’s movements, such as walking or breathing. This harvested energy is then used to power a light source that shines light on the photosensitizer.
In a study, researchers tested the ACEL mPDT device on mice with chronic wounds infected with MRSA. The device was effective at killing bacteria and promoting wound healing. The researchers also found that the device was biocompatible and non-toxic.
The ACEL mPDT device has the potential to be a new and effective treatment for chronic wounds. It is wearable, self-powered, and safe for use. More studies are needed to evaluate its long-term safety and efficacy, but it has the potential to improve the lives of people with chronic wounds.
