Researchers from*Tel Aviv University, the Hebrew University of Jerusalem, Israel, and Newcastle University have created a proof of concept artificial retina that may one day help treat a number of eye diseases, including age-related macular degeneration. The device is made of semiconductor na**rod-carbon na**tubes and doesn’t have*any metal wire components. The resulting film is both flexible and light sensitive, allowing it to be shaped into the form of a natural retina.

The researchers tested the new device on chicks whose retinas were still **t light sensitive, and showed that the artificial retina was able to induce neuronal activity in response to light.

Some details from the study abstract in Na** Letters:

A plasma polymerized acrylic acid midlayer was used to achieve covalent conjugation of semiconductor na**rods directly onto neuro-adhesive, three-dimensional carbon na**tube surfaces. Photocurrent, photovoltage, and fluorescence lifetime measurements validate efficient charge transfer between the na**rods and the carbon na**tube films. Successful stimulation of a light-insensitive chick retina suggests the potential use of this **vel platform in future artificial retina applications.
