Quantum dots in the eye
New Scientist report a new method of improving vision was patented. The idea is to amplify the light hitting the retina for vision impaired. Nanoscale specs of semiconductor = quantum dots are injected into the eye. They fluoresce when hit by photons and thus make light hitting retina cell brighter. Tests on rats shown that rats with quantum dot injected have more retina electrical activity. No words if improvement in the sight of the rats was actually observed.
