In hope to restore sight to the blind Scientists are developing ‘artificial retina’

A artificial retinal is in process of development in joint effort between Tel Aviv College in Israel and Linköping College in Sweden.  Manufactured utilizing widely-available and cheap organic pigments used in printing inks and cosmetics, it comprises of little pixels like a computerized camera sensor on a nanometric scale. Specialists trust that it can reestablish sight to blind individuals.
Experimenter direct by Eric Glowacki, head reseacher of organic nanocrystals which is a subgroup of laboratory of organic Electronics have have advanced a small photoactive film that converts light impulses into electrical signals which in turn stimulate nerve cells.The swedish team, specilized in nanomaterials  and electronic are working with scientists of israel, austria and italy to advance the technology. Yael Hanein group carried the experiments at Tel Aviv University in Israel who are world-leader in combining electronic and nervous system 

The results have recently been published in the scientific journal Advanced Materials.

Eric Glowacki said

We have optimised the photoactive film for near-infrared light, since biological tissues, such as bone, blood and skin, are most transparent at these wavelengths. This raises the possibility of other applications in humans in the future,
He describes the artificial retina as a microscopic doughnut, with the crystal-containing pigment in the middle and a tiny metal ring around it. It acts without any external connectors, and the nerve cells are activated without a delay. 


The response time must be short if we are to gain control of the stimulation of nerve cells,

says David Rand, postdoctoral researcher at Tel Aviv University.
Here, the nerve cells are activated directly. We have shown that our device can be used to stimulate not only neurons in the brain but also neurons in non-functioning retinas.
