Daily insulin injections could be a thing of the past in the future of people with diabetes thanks to an invention by researchers in the U.S. The smart insulin patch, created by researchers at the University of North Carolina, can detect increases in blood sugar levels and secrete doses of insulin into the bloodstream whenever needed. Patients with type 1 and advanced type 2 diabetes try to keep their blood sugar levels under control with regular finger pricks and repeated insulin shots, a process that is painful and imprecise. John Buse, MD, PhD, co-senior author of the PNAS paper and the director of the UNC Diabetes Care Center, says “Injecting the wrong amount of medication can lead to significant complications like blindness and limb amputations, or even more disastrous consequences such as diabetic comas and death. More pre-clinical tests and subsequent clinical trials in humans will be required before the patch can be administered to patients, but the approach shows great promise.
