DNA used to make nano computers

Scientists have built simple machines out of DNA, which can be used to make nanotech sensors, amplifiers and even a molecular computer.

The DNA machines can relay discrete bits of information through space or amplify a signal, said Yonggang Ke, an assistant professor from Georgia Institute of Technology in the U.S. “In the field of DNA-based computing, the DNA contains the information, but the molecules are floating around in solution,” Mr. Ke said.

“What’s new here is that we are linking the parts together in a physical machine,” he said. Researchers showed that they could build rectangles and tubes of array units.
