Chinese Scientists Restore Vision and Enable Infrared Sight Using Tellurium Nanowires
Researchers from Fudan University in China have developed a revolutionary retinal implant based on tellurium nanowires that not only restores vision in blind mice but also allows macaques to see in the infrared spectrum. This breakthrough in neurotechnology opens new possibilities for treating blindness and enhancing human sensory capabilities.
The implant is a mesh of tellurium nanowires that can convert both visible and infrared light into electrical signals sent directly to the brain. Thanks to the unique photoelectric properties of tellurium, the device requires no external power supply. In experiments, blind mice fitted with the implant showed recovery of pupillary reflexes, visual cortex activity, and improved pattern recognition.
Moreover, when the device was implanted into sighted macaques, they gained the ability to perceive infrared light at wavelengths up to 1550 nm—a range inaccessible to typical mammalian vision. This achievement has broad potential applications, ranging from medical and military to industrial uses.
The implant demonstrated high biocompatibility and no toxic effects over a 60-day observation period. Although human clinical trials have not yet begun, the researchers believe the technology has the potential to restore vision in retinal diseases such as macular degeneration, and even to expand the visible light spectrum for healthy individuals.
