Nanoparticle injection could lead to night vision

Mice injected with photoreceptive nanoparticles were able to perceive infrared light without equipment, opening the possibility that the technique could someday allow people to see in the dark. Researchers at the University of Science and Technology of China and the University of Massachusetts Medical School in Boston used a subretinal injection technique to implant tiny antennae, which converted infrared light into visible green light.
