Researchers in Germany have developed a way to make simple, self-assembling DNA 'robots' that can rotate and function like latches. Combined, they can be used as nano-scale cargo carriers that respond ...

DNA robots can be programmed to explore new territories, pick up cargo, sort it into categories, and then deliver each cargo type to a defined location. Conceptual illustration of two DNA robots (2).

Nanotech systems based on DNA may be on the verge of becoming very large and complex, if not immediately useful to medicine or manufacturing. Researchers have combined simple strands of DNA into the ...
