Organic Electrodes Offer Non-Invasive Electrotherapy
The green areas in the zebrafish brain indicate that the nerve cells send electrical signals when the implanted electrode transmits external stimuli. The characteristic shape indicates successful stimulation. No tissue damage was observed.Researchers from Lund University and Gothenburg University have developed a novel method for integrating temporary organic electrodes into biological systems, allowing for non-invasive electrotherapy treatments. The technique involves injecting a solution of nanoparticles into the tissue, which then self-organizes into conducting structures that seamlessly integrate with the body's cells. This approach eliminates the need for surgery to implant metal electrodes, making electrotherapy more accessible for various medical conditions. The electrodes formed by this method cover larger areas and can be excreted from the body after treatment, offering a promising avenue for non-chronic disease therapies.
