Young scientists from ITMO University proposed a new type of optical nano-sensors. Their operating principle is based on the interaction of light in thin films: a similar effect can be observed in soap bubbles. Such sensors can be quickly manufact...

Injected into their eyes, the particles alter infrared light to make night vision possible.
How it worked: The nanoparticles stick to the eye’s retinal cells, which convert light into electric signals. They turned infrared light, which mice cannot see, into green light, which they can.
Tests: We still haven’t worked out how to get mice to talk, so to check to see whether the nanoparticles worked as expected, the team shined infrared light into their eyes. The pupils of mice given the injection contracted, whereas the control group’s pupils did not. In another test, the mice were allowed to roam around two chambers, one dark and one lit with infrared. The ones that had received the injection spent more time in the dark area (indicating they found the infrared chamber too bright).
Long lasting: The tests, published in Cell, found that the infrared effect lasted in the mice for 10 weeks, causing no long-term damage (though some had cloudy corneas for up to two weeks).
Would it work in humans? The team from the University of Science and Technology of China believe it will. It could potentially fix red color blindness, for example. They’ve filed a patent for their work, which they reckon could lead to both civilian and military applications. Whether someone would volunteer for a sight-altering eye injection rather than just opting for night vision goggles remains to be seen.
