Skin ***** Automatically Releases Insulin to Control Blood Sugar

A collaboration between scientists at*University of **rth Carolina at Chapel Hill, **rth Carolina State University, and*Changchun Institute of Applied Chemistry at the*Chinese Academy of Sciences has developed a **vel skin ***** that delivers insulin in response to high levels of measured glucose. The tech**logy, if proven to work successfully in humans, may have a transformative effect on diabetes management.

The ***** has a bunch of microneedles that are sensitive to glucose, breaking up when a high concentration of the sugar is detected. The needles are hollow and each contains a small dose of insulin that is released when the needles degrade.

The needles are made from a peroxide-reacting polymer that is loaded with glucose oxidase. When the glucose oxidase reacts with glucose, H2O2 is produced and the needles disintegrate and release their cargo of insulin.

The ***** was trialed on lab mice who underwent spikes in glucose levels. The ***** successfully controlled those and reduced the blood glucose levels to **rmal within two hours of a glucose spike.
