New device may restore vision

Researchers at the Tel Aviv University's School of Electrical Engineering have developed a revolutionary device that is able to spark neuronal activity in response to light. The device is a combination of semiconductor nanorods and carbon nanotubes that creates a flexible film. This artificial retina would replace a damaged retina. Researchers tested this artificial retina on chick retinas that were not light sensitive yet in order to demonstrate the artificial retina's ability to spark neuronal activity when exposed to light. This new artificial retina is more durable, flexible and efficient than current technologies that are available. The device is more compact and wireless and has higher spatial resolution. While researchers were able to prove that the device is able to stimulate neurons with light, much more research is needed to prove that it is compatible in animals over a long period of time. It is hoped that this groundbreaking technology will eventually be available to people suffering from vision loss due to macular degeneration and other diseases.*
