No one has given up their night vision goggles yet, but scientists working in the United States and China have developed a technique they believe could one day allow humans to see in the dark.

The technique involves injecting into the eyes particles that act as small antennas that capture infrared light – wavelengths invisible to humans and other mammals – and convert it into lengths. visible wave. Mammals can see wavelengths in only a portion of the electromagnetic spectrum, and the new technique is designed to expand that portion.

Injections of nanoparticles have not yet been tried in humans, but experiments on mice have shown that they confer the ability to see infrared light without disturbing the perception of light in the body. visible. The effect worked during the day and night and lasted several weeks. The rodents were left unharmed once they disappeared.

Gang Han, a chemist from the University of Massachusetts Faculty of Medicine and co-author of a new article describing the research, said in a statement that this technique could help better understand visual perception and possibly new methods of color treatment. blindness.
