This new insulin patch could soon replace injections for diabetics

A new ‘smart patch’ lined with painless microneedles full of insulin has been developed by researchers in the US in an effort to do away with the uncomfortable injections that have become a part of life for the millions of type 1 diabetics around the world who need to manually regulate their hormone levels.

The 4-cm patch features more than a 100 of these eyelash-sized microneedles, and not only go they contain enough insulin to provide the same dosage as a single injection, but they also contain glucose-sensing enzymes that can identify when blood-sugar levels are too high and release the insulin into the blood stream.

“We have designed a patch for diabetes that works fast, is easy to use, and is made from nontoxic, biocompatible materials,” said one of the researchers, Zhen Gu, from the joint  University of North Carolina/NC State’s Department of Biomedical Engineering. “The whole system can be personalised to account for a diabetic’s weight and sensitivity to insulin, so we could make the smart patch even smarter.” Source: This new insulin patch could soon replace injections for diabetics
