Glowing Robot Eye Injections

Bradley Nelson Created a New Technology That May Save Your Eyesight

— May 13, 2013 — Tech
This new technology may save your eyesight. Bradley Nelson is a professor of robotics and intelligent systems at ETH-Zurich. Leading a team of researchers, he has created tiny devices that will help save your eyesight. These tiny robotic devices are injected into the eye and can be steered through the eye’s fluids with external magnetic fields.

Nelson and his team of researchers have done this by coating these micro-robots with nanospheres made out of a special dye that will turn the devices into oxygen detectors. When they are exposed to a specific wavelength of light, the dye glows. A Fluorescence that disappears quickly will then indicate high amounts of oxygen that are surrounding the dye. If the dye fades slowly, this indicates low amounts of oxygen. Essentially the new oxygen-sensing robots will indicate when the blood flow to the eye is restricted, which is generally the result of vision loss.
