Speedy DNA nanorobot could lead to molecular factories

DNA-based robots promise all kinds of microscopic machinery, but theres a major obstacle: theyre slow. Existing designs that use biochemical processes for movement can take hours to shuffle molecules around, which makes them utterly impractical for anything time sensitive. That might not a hurdle for much longer. Scientists have developed a DNA nanorobot (specifically, an arm) that uses electric fields to move a whopping 100,000 times faster than previous examples, even though it…..
