A Chemical Brain To Control Nanobots

Nanotechnology is perhaps the most rapidly advancing new technology out there right now. All kinds of nanomachines based on biochemical mechanisms, tiny structures of metal or other techniques are being created and studied in universities and laboratories around the world.

Scientists have now created a device two billionths of a metre in size that could work as a chemical ‘brain’ for a group of nanomachines. Potentially this could lead to their use in medical techniques such as nano-surgery on tumours.

“If [in the future] you want to remotely operate on a tumour you might want to send some molecular machines there,” explained Dr Anirban Bandyopadhyay of the International Center for Young Scientists, Tsukuba, Japan. “But you cannot just put them into the blood and [expect them] to go to the right place.”

Dr Bandyopadhyay believes his device may offer a solution. One day they may be able to guide the nanobots through the body and control their functions, he said.

“That kind of device simply did not exist; this is the first time we have created a nano-brain,” he told BBC News.
