[China Pharmaceutical Network Technology News] With the development of smart technology and nanotechnology, high-tech nanotechnology is applied to all walks of life. It is reported that researchers from the Ramat Ganabalan University in 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. IDoBachelet, the 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).
This technique can detect changes in brain activity and trigger a nano-robot to release anti-epileptic drugs in the brain when it detects signs of seizures. This technique can respond to an individual's cognitive state of mind and thereby control the switching of active molecules online. Researchers claim that this technology can be applied to humans to observe changes in brain activity during schizophrenia, depression, or seizures.
The patient is injected with a nano-robot carrying the drug and the brainwave activity is monitored by a cap with a sensor. When a specific pattern of brainwave activity occurs, the electromagnet in the cap can be triggered to open the cavity shell of the nano-robot and release the drug.
SacharArnon, the first author of the paper from the Interdisciplinary Center, said that robots can also be adapted to your needs. For example, in the treatment of epilepsy, it can detect signs of seizures from brain activity and immediately release anti-epileptic drugs from nano-robots.
SacharArnon also added that this technology may also be applied outside of medicine. “Imagine if you get an accurate amount of alcohol that keeps you happy and not drunk. I think our research has just begun.â€
