Afraid to pierce the needle for pain? And if it doesn’t hurt! Researchers at IIT Kharagpur discovered such a needle. That needle is thinner than thin hair. Because, where human hair is 50–70 mm thick, the density of this needle is only 55 mm. A team of researchers from one of the best educational institutions in the country has also discovered a suitable pump. They call it micro pump. The needle is also known as the micro needle.

Researchers from the Department of Electronics and Electrical Engineering, IIT Kharagpur, claim that the very thin needle penetrates the skin very finely and is able to deliver medicine to the body without causing a single drop of pain. It should be noted that in several countries, including the United States, this transdermal, painless way of administering drugs from one side to the other, is very popular and widely used.

In the same way that conventional syringes are filled with liquefied medicine and pumped into the body through a needle, the same is true, the medicine will enter the body through a micro needle by pressing on a micro pump. But in that case, the researchers said, it would not be so painful. They said the needle they discovered was so narrow that it did not affect any nerves in the body, so there was no pain.

Professor Tarunkanti Bhattacharya said, ‘‌We have made micro-needles made of high-strength glass carbon that can withstand the skin’s resistance. And the micro pump helps to increase the flow rate of drug molecules in a controlled and precise manner. We have worked harder on these micro needles and micro pumps to provide controlled medicine. ”

The project is funded by the Ministry of Electronics and Information Technology of the Central Government and the Department of Science and Technology. A statement from IIT Kharagpur on Friday said the micro-needles and micro-pumps, which supply medicines in accordance with medical protocols, had been successfully tested on the animals. Researchers have already applied for a patent. The success of the organization has been published in the journal Nature and IEEE.
