A strategy life like
A man has been able to control nanorobots residing inside living things with the sole use of his thoughts for the first time. The equipment released a drug within the cockroach in reaction to the man’s brain action – a strategy that may be of help for curing disorders related to the brain like ADHA and schizophrenia. Getting drugs to the target site could be a great challenge.
A majority of drugs are spread in the body or transported via the blood stream over time –and you have to helplessly bear the side effects in anticipation of the drug to wear off. Two groups in Israel, one in Ramat Gan and another in Herzliya called, Bar Ilan University and Interdisciplinary Centre respectively, have come up with a scheme that permits specific control when a drug is not passive in the body.
The team has constructed nanorobots with the help of DNA, creating shell-like figures that drugs can be secured in. These bots have gates which bear locks formed from nanoparticles of iron oxide. With the help of the heat formed using electromagnetic energy, the lock can be opened up and the drug can be exposed at the target site. Since the drug stays bound to the DNA, the opening and closing of the gate controls a body’s exposure to the drug.
In order to make the DNA bots respond to the thoughts of a person, the group educated a computer algorithm to differentiate between a human’s brain activity when at rest and when conducting mental arithmetic. The group then introduced a luminous drug to the bot and was injected into a cockroach which sat in an electromagnetic coil.
An EEG cap was given to a person to wear that measured brain activity, either stay at rest or to conduct calculations mentally. The electromagnetic coil was connected to this cap, thus powering it on when the person calculated and off when he was at rest. The team confirmed that the technique worked by observing as to when the luminescence was shown inside several cockroaches.
A member of the team at the Interdisciplinary Centre, Sachar Amon says that the algorithm could be more skilled to track down other forms of activity of the brain. “It is possible to tracecircumstances of the brain which could be responsible for schizophrenia or ADHD, for instance. It could be revised to suit the needs of the individual.”
The clue would be to spontaneously activate the release of a drug when in need. Take for instance; people would not always know as to when they would need medication – prior to an intense occurrence of schizophrenia. If it could be detected by an EEG that it was to arrive, it would probably stimulate the discharge of a preventive drug.
The mechanism should be able to reduce the unwanted side effects that come along, since the bots can conveniently close and open their gates as per requirements. Fine tuning the DNA bots could also give assurance that they would be target specific regarding to the cells in the body, therefore subsidizing harmful reactions elsewhere within the body.
This could be achieved by fastening molecules that could bind to receptors on the exterior of definite types of cells to the surface of the bots. But this kind of scientific machinery is not yet ready to be tried in humans.
The formation needs a smaller, more transportable process of quantifying brain activity; something Amon believes is not a long way to go. The group sees a person wearing a tiny, EEG device which looks similar to that of a hearing aid, to keep note of brain activity and identify when a drug would be needed.
An example would be, when a person having ADHD, has a concentration which is about to lapse, the electromagnetic field necessary to discharge the drug dose of Ritalin would be triggered by a smart watch creating it. Such type of permutations of various devices could come of aid to treat the depressed and other people suffering from conditions of the brain that could be a great task to deal with.
Not only that, but it would also permit people to consciously trigger when they willingly want a drug to be discharged by calling upon particular thoughts. Again when asked Amon commented that, “This could be directed by people in various orders. Picture if you could supply the precise amount of alcohol that you would wish to keep yourself in a joyful state but not too much to be drunk. It is kind of silly, but such things are possible and can take place.
I think so far we have initiated the briefest research to discover something concealed.” In no time, they would possibly hit the ground running and so would be those who are schizophrenic and suffering from ADHD.
