Scientists at the University of Science and Technology of China injected tiny nanoparticles that bind to the retina into the eyeballs of test mice, granting them what the [researchers called]() "super vision." ## With Great Power In the new research, described in [a paper]() published in the journal *Cell* today, the researchers injected "ocular injectable photoreceptor-binding upconversion nanoparticles" into the eyes of mice. The stunning result: after the injection, the mice were able to see normally invisible near-infrared light — both humans and mice are normally unable to perceive light with wavelengths longer than 700 nanometers — effectively extending "mammalian vision," according to the paper. The theory is that the nanoparticles bound with the retinal cells responsible for converting light into electric signals. To test the procedure, the scientists shined infrared light straight into the mice's eyes to see if they would react. The pupils of the mice that were injected with the nanoparticles pupils contracted, showing that they could "see" the infrared light. Pupils of control mice without the injection didn't contract. ## Future Vision Luckily, the injection didn't appear to interfere in any way with the mice's normal eyesight. The scientists also didn't notice any other long-term harm except for corneas that clouded over — but only for a day or two. So what could be the applications of this kind of technology? The scientists believe that these kind of nanoparticles could help repair vision in humans who experience loss of retinal function. It could also prove far less invasive than other conventional vision repair methods, and with fewer side effects. **READ MORE:** [Mice given ‘night vision’ by injecting nanoparticles into their eyes]() \[*New Scientist*\] **More on night vision:** *[Cannabis May Have Night Vision Enhancing Effects]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
