DNA origami nanorobots use long DNA chains that are folded into specific shapes, creating tiny containers. They can recognise specific cell types using molecules called aptamers. Once they reach their target cells, they can deliver payloads such as drug molecules.
“In essence, the approach co-opts a number of strategies of our immune systems, with the robots playing the role of white blood cells that hunt down problematic cells and destroy them,” the BBC reported in 2012.
The BBC was reporting on laboratory tests that had been conducted by researchers at the Wyss Institute at Harvard University.
Harvard’s DNA nanorobot is a clam-like bot that can release its drug payload only when it reaches and identifies its target, cancer cells.
