DNA robots pave way for microscopic factories
[ Wed, 12 May 2010 18:42:47 GMT ]

A molecular nanorobot dubbed a "spider" and labeled with green dyes traverses a substrate track built upon a DNA origami scaffold. It journeys towards its red-labeled goal by cleaving the visited substrates, thus exhibiting the characteristics of an autonomously moving, behavior-based robot at the molecular scale.New DNA-based machines that can perform more complex tasks with greater autonomy than ever before are helping to lay the foundation for microscopic factories and nano-sized robots of the future.
