DNA helix
Electrical circuits made from have been a theoretical possibility – and never created – until now. What could this mean for the future of computing?

Excerpt from techtimes.com


Electrical circuits on DNA could soon become a reality. Computer circuits could be designed on the genetic structure of all living beings, providing processors significantly faster than current technology.

Computers have become over the sixty , as well as more powerful. Transistors are critical to the operation of the machines, but a minimum distance between the components is required to prevent interference between the devices. This has limited designers from creating processors much smaller than modern technology.

Molecular electronics could get around this challenge, if researchers could find a way to that self-assemble into circuits. So far, that has not been achieved by any of the groups working on the task. The only that self-organize in complex forms in nature are DNA, making these structures obvious for researchers looking to develop electrical processors. However, no large DNA have been successfully shown to carry an electrical signal in a manner which could prove useful in a processor.

Hebrew University of Jerusalem researchers collaborated with other scientists from around the world to develop four strands of DNA capable of carrying such a charge.

Researchers believe this could be the greatest breakthrough in DNA-based electrical circuits in the last ten years.
