The nanobots have two arms and is said to swim in a “freestyle” stroke, or front crawl, when guided with magnets. They have three main parts, and are said to be approximately the size of a single blood cell.
The super-small machine was built by Joseph Wang and his colleagues at the University of California at San Diego. Co-workers at the Harbin Institute of Technology in China and the Israel Institute of Technology were also involved. Continue reading Tiny nanobots swim through blood stream to deliver medicine
