Researchers use magnets to control DNA-based robots

Carlos Castro, associate professor of mechanical and aerospace engineering, and Ratnasingham Sooryakumar, professor of physics, have devised a magnetic control system to make tiny DNA-based robots move on demand–and much faster than recently possible. The researchers report that the control system reduced the response time of prototype nano-robot components from several minutes to less than a second. The discovery could one day enable nano-robots to manufacture objects–such as drug-delivery devices–as quickly and reliably as their full-size counterparts.
