Needle thinner than a human hair developed by IIT Kharagpur, will ensure painless drug delivery

A needle thinner than a human hair has been developed by researchers from the Indian Institute of Technology at Kharagpur. The researchers have also developed a micro-pump for injecting drugs to patients in a painless way along with the micro-needle. The micro-pump and the micro-needle will be fed into the transdermal drug delivery systems. The needles are so small that they cannot touch the nerves in the skin.
