Nanoscale Robots Made of DNA

Scientists have created a robot that is made from DNA molecules, and while DNA has already been used to construct things on the nanoscale, this tiny 'robot' can move. The technology takes advantage of the electrically charged nature of DNA; when a charge is applied to the molecular arm, it can be manipulated and tracked to specific points. The movement occurs rapidly as well.

The developments have opened the door to true, 3D printed molecules that could be used in countless ways. Everything from industry to medicine might benefit from this technology. Learn more about it from the video by Science.
