Nanotechnology has already had a significant impact on the world of medical science – however the next generation of nano-scale medical technology will blow your mind. For example, researchers from the University of British Columbia are currently working on a line of nanobots that will aim to diagnose and heal the body from the inside. In order to accomplish this amazing feat they have developed artificial muscles that are extremely flexible and strong enough to rotate objects a thousand times their own weight. By spinning carbon nanotubes into helical yarns, researchers were able to control the yarn with an electrochemical charge that causes them to twist and untwist. The muscle can be incorporated into bots with artificial flagella, or tiny tails that would rotate to propel them.
