Seeing IR (infrared). Low energy IR (800 nm) radiation cannot be detected by human eyes and those of mice 🐁 due to the fact that our eyes 👀 have photoreceptors that absorb light in the visible spectrum (380-740 nm). . However, recent research in vision shows that it maybe possible for humans to see IR in the near future. Scientists injected nanoparticles containing rare-earth metals conjugated with the protein concanavalin A that acts as a glue to attach the nanoparticles to the rods and cones in the eyes of mice. . Further experiments showed that not only did the nanoparticles bind to these photoreceptor cells, but also activated them by converting the low energy IR to higher energy green light 💡 that can be detected by mice. Thus, the mice were able to see IR and find themselves out of a maze with IR cues. . Science article: https://www.sciencedaily.com/releases/2019/02/190228141412.htm .
