DNA Nanorobots Pick Up And Sort Molecules

An autonomous molecular machine, made of a single strand of DNA, that can autonomously “walk” around a surface, pick up certain molecules and drop them off in designated locations has been developed by scientists at California Institute of Technology. Lulu Qian, assistant professor of bioengineering, explains: The researchers constructed three basic building blocks that could be used to assemble a DNA robot: a “leg” with two “feet” for walking, an “arm” and “hand” for picking up cargo, and a segment that can recognize a specific drop-off point and signal to the hand to release its cargo.
