Tiny robot walker made from DNA

Scientists have created a microscopic walking robot using only the building blocks of life: DNA. The tiny walker is only 10 nanometres long and has been described as a major step forward in nanotechnology. A New York University team created the robot using DNA legs that move along a footpath, which is also based on DNA.? The legs move by detaching themselves from the footpath, moving along it and then reattaching themselves, New Scientist reports. DNA is an ideal material to build the robot from, because DNA chains easily pair up. – BBC
