Scientists report they have successfully developed and tested the world’s first ultrathin artificial retina that could vastly improve on existing implantable visualization technology for the blind. The flexible device, based on very thin 2D materials, could someday restore sight to the millions of people with retinal diseases. And with a few modifications, the device could be used to track heart and brain activity.

“This is the first demonstration that you can use few-layer graphene and molybdenum disulfide to successfully fabricate an artificial retina,” Nanshu Lu, Ph.D., says. “Although this research is still in its infancy, it is a very exciting starting point for the use of these materials to restore vision,” she says, adding that this device could also be implanted elsewhere in the body to monitor heart and brain activities.
