Nanotech helps blind hamsters see

Nanotechnology has restored the sight of blind rodents, a new study shows.

Scientists mimicked the effect of a traumatic brain injury by severing the optical nerve tract in hamsters, causing the animals to lose vision.

After injecting the hamsters with a solution containing nanoparticles, the nerves re-grew and sight returned.

Writing in the Proceedings of the National Academy of Sciences, the team hopes this technique could be used in future reconstructive brain surgery.
