A vision physiologist and a nanoparticle expert have injected nanoparticles that convert infrared light into visible light into the eyes of mice. The injections gave the mice the ability to see in the dark for as long as 10 weeks. The researchers say the technique could work safely in humans, and be especially useful for troops in nighttime military operations. Brad Allenby, a Fulton Schools professor of engineering and ethics, and founding chair of the Consortium for Emerging Technologies, Military Operations and National Security, says more studies would be needed to ensure such injections have no negative effects in humans, but that enhanced visual capability would give troops and security personnel a significant advantage.
