NANO-FACTORIES of the future could be equipped with DNA strands acting as nanoscale robot arms that will pick up and assemble molecular-scale objects.
Such long-sought nanorobots are now a step closer thanks to a team led by Nadrian Seeman of New York University in New York City, which has built a machine in which a DNA arm is attached to a body that is also made of DNA. The researchers were then able to make the arm move back and forth by washing the whole structure with a solution containing fragments of DNA that bind to different parts of the…
