artificial retinas

The development of artificial retinas still faces many challenges: the implants should provide long-term light sensitivity, should have high spatial resolution, should not contain wires, and should be made of materials that are biocompatible and mechanically flexible...In a new paper published in Nano Letters, researchers at Tel Aviv University, The Hebrew University of Jerusalem, and Newcastle University have found that a film containing carbon nanotubes and nanorods is particularly effective for wire-free retinal photostimulation...
