Can nanobots have muscles? Researchers have made very strong, flexible muscles that could be used by nanobots to travel around the body diagnosing and treating medical conditions. As flexible limbs much like octopus tentacles, artificial muscles can move objects a thousand times heavier. Thinner than a human hair, the "yarns" are cheap to make. They could potentially be used for pumps, valves, stirrers and flagella for drug discovery. They were created by applying an electrochemical charge to spun carbon nanotubes making them twist into helical yarns. They are ideal to attach to bots as a tiny tail, a flagella, to propel the bot forward. This was a truly international breakthrough. Participants in the work were the University of Wollongong, Australia, the University of Texas and Hanyang University of Korea. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blog
