Artificial Semiconductor Wireless Retina Already Proving Itself in Lab Study
Artificial Semiconductor Wireless Retina Already Proving Itself in Lab Study
http://cdn.medgadget.com/wp-content/.../11/fj02ee.png 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.Study in Na** Letters:*Semiconductor Na**rod–Carbon Na**tube Biomimetic Films for Wire-Free Photostimulation of Blind Retinas… Press release:*Artificial retina could someday help restore vision… http://feeds.feedburner.com/~ff/Medgadget?d=yIl2AUoC8zA http://feeds.feedburner.com/~ff/Medgadget?d=qj6IDK7rITs http://feeds.feedburner.com/~ff/Medg...uE:gIN9vFwOqvQ http://feeds.feedburner.com/~r/Medgadget/~4/C6-1rGzSPAg |
