The nanotechnology works by binding with the retinal cells in the eye that convert light into electric signals.
Because infrared wavelengths are too long to be absorbed by photoreceptors, we are not able to perceive them.
The experiment was successfully tested on mice who were given a simple injection containing nanoparticles directly into their eyes.
After ten weeks, when the particles separated from the photoreceptors, the rodents normal vision was still intact.
According to scientists, they could make changes to a humans vision to detect a wider spectrum of colors.
But the nanoparticles capture the longer infrared wavelengths and emit shorter wavelengths that retinal cells can detect.
This converted light peaks at a wavelength of 535 nanometers, so the mice see infrared light as green.
To think that you might inject these nanoparticles and have them work is incredible.
