Researchers from the Inter-disciplinary Center in Ramat Gambalan, Israel, and the Herzliya Interdisciplinary Center in Israel have used DNA folding structures to create nano-robots with hollow-shell structures. With this nano-robot, doctors can control the release of drugs over a period of time, releasing only small doses of drugs at a time. They claim that this technology can be used to treat brain diseases such as schizophrenia, depression, and attention deficit disorder.
The drug is first chemically treated, using iron oxide particles to "lock" the drug, and then placed in the hollow shell of the nano-robot. Next, an electromagnet is used to heat and destroy the shell of the DNA structure, thereby releasing the drug. Under the leadership of Dr. IDo Bachelet, chief scientist of nanotechnology, they have been able to use human brain waves to control this process.
To achieve brainwave control, they train a computer algorithm to detect whether the human brain is in a complex change in thinking activity. When the brain activity changes, the computer triggers an electromagnet to unlock the nano-robot injected into the body. The researchers released a fluorescent protein in the sputum to track the rate of release.

Researchers who are writing a journal in the Public Library of Science said: "As a theoretical demonstration, we demonstrate the activity of DNA robots, and the use of the brain to handle complex transactions triggers the cellular effects of the insects (蟑螂).

The researchers injected nanobots into the sputum to test their techniques, using sensors to detect changes in human brain activity, thereby activating electromagnets and releasing the contents of nanobots.
