TAU researchers develop groundbreaking wireless material capable of sparking neuronal activity in response to light
The aging process affects everything from cardiovascular function to memory to sexuality. Most worrisome for many, however, is the potential loss of eyesight due to retinal degeneration.
New progress towards a prosthetic retina could help alleviate conditions that result from problems with this vital part of the eye. An encouraging new study published in Nano Letters describes a revolutionary novel device, tested on animal-derived retinal models, that has the potential to treat a number of eye diseases. The proof-of-concept artificial retina was developed by an international team led by Prof. Yael Hanein of Tel Aviv University‘s School of Electrical Engineering and head of TAU’s Center for Nanoscience and Nanotechnology and including researchers from TAU, the Hebrew University of Jerusalem, and Newcastle University.
“Compared to the technologies tested in the past, this new device is more efficient, more flexible, and can stimulate neurons more effectively,” said Prof. Hanein. “The new prosthetic is compact, unlike previous designs that used wires or metals while attempting to sense light. Additionally, the new material is capable of higher spatial resolution, whereas older designs struggled in this area.”
A natural shape
The researchers combined semiconductor nanorods and carbon nanotubes to create a wireless, light-sensitive, flexible film that could potentially replace a damaged retina. The researchers tested the new device with chick retinas which were not yet light sensitive to prove that the artificial retina is able to induce neuronal activity in response to light.
Patients with age-related macular degeneration (AMD), which usually affects people age 60 or older who have damage to a specific part of the retina, will stand to benefit from the nanotube device if it is proved compatible in animals over the long term.
