DNA robots: Nano-spiders gearing to enter our bodies for good

A team of researchers Columbia University have developed spider robots that measure only four nanometres across (100,000 times smaller than the diameter of a human hair). These microscopic robots are created out of DNA molecules which are good for chores like walking, turning and can even create tiny products of their own on a nano-scale track. These robots done at the molecular level are programmed DNA-walkers, which are created with legs to walk around two-dimensional landscapes autonomously. The spider bots respond like the elementary robots moving about slowly, like 100 nanometers in 30 minutes to an hour. These robots are a significant step in the field of molecular robotics, which may be juvenile today, but would someday grow with bots like these holding important medical applications.
