DNA Nanorobots



Scientists at China's Nanjing University have engineered a nanorobotic arm, from strands of DNA, measuring just 150x150x8 nanometers. That makes these nanoid robotic arms a million times smaller than a red blood cell. At work, they are able to move and place individual atoms and molecules with an accuracy of 100 percent.
The nanorobotic arm is constructed using DNA origami. DNA origami are large strands of DNA that fold in precise ways, triggered by interaction with a few hundred short DNA strands.
The products, around 100 nanometers in diameter, are eight times larger and three times more complex than those built with a simple crystalline DNA array, vastly expanding the space of possible structures.
