Micro needles take drugs to every corner of the brain

Scientists at MIT Institute of Technology (UK) have developed a device that looks like it can deliver drugs to every corner of the human brain.

Usually when treating diseases related to disorders of parts of the brain, doctors often give patients to take medicine or intravenously. Although the drug still reaches the 'sick' organs, it affects the whole brain, causing other cells in the brain to be damaged and often causing unnecessary side effects.

The NDS has successfully tested on mice and primates.

The structure of the IDS needle looks quite simple but is likely to wriggle very high in the human body.

To solve this problem, MIT scientists have developed a micro needle that can deliver a sufficient amount of medication to the necessary parts of the brain.

The needle is MiNDS (Micro-neurotransmitter delivery system) , consisting of small ducts that are connected to a main tube that delivers the drug. Their size is only equal to a human hair. Each drug tube or channel is 30 micrometers in diameter and can be used to deliver different drugs to the very smallest cells in the human brain.

MIT scientists have successfully tested mice. The tubes were connected to a micro pump placed under the skin and inserted into a small area of ​​the mouse without causing any impact on other areas of the brain.

According to the researchers, these tubes can be manufactured to any length or thickness to be used for many objects, including humans. In particular, instead of using tubes, these channels of drug delivery may also be in the form of optical fibers to treat neurological disorders with light or electrodes, monitoring how brain activity occurs after use medicine.

Now scientists are finalizing the final steps to bring this micro needle into widespread use.
