ROBOTS THAT TRAVEL THROUGH YOUR EYEBALL
A joint Chinese-German research team have created tiny spiral-shaped robots that are injected in the eyeball to deliver medicine.
Researchers created the microbots using nanoscale 3D printing, a technique that produces items 200 times smaller than the width of a human hair. They then injected the little bots into the eyes of dead pigs after which they were controlled magnetically.
Although the thought of bots burrowing through your eyeball might make your skin crawl, this could be the future of eye medicine, especially for treating diseases such as glaucoma. It allows eye drops to be delivered 10 times faster and is far more accurate.
The scientists are preparing to test the bots on living animals.
