Wow! Scientists are one step closer to creating molecular robots that may eventually perform very complex tasks, such as building nanomolecules… or delivering drugs to targeted diseased tissues. They have constructed DNA-based robots that can walk along a specific path, unaided, or, collect various nanoparticles along an assembly line. This news is from two studies published this week in Nature.
