IR-sensitive Nanoparticles Give Mice IR Vision And Humans Could Be Next

In another indication of the frightening pace at which nano and biotechnology is now moving, scientists have developed a technique that gives mice a near infra-red spectrum of vision, allowing them to see in the dark. Night goggles use infrared light and researchers have found a similar effect can be achieved by injecting specially designed ‘nanoparticles’ directly into the eyes of mice. And humans could follow.

 

After injection, the nanoparticles that gave the mice ‘super sight’ sit at the back of their retinas. From that position, they convert near infrared light that is normally invisible to the eye into a form of visible light. Effectively meaning the mice could see in the dark in a way similar to how they would if fitted with a set of high-tech night goggles like those used in the military. Over several weeks, the body gradually removes the nanoparticles without any visible ill effects on the mice.
