New Insulin Patch for Painless Treatment of Diabetes? - PSSA

New Insulin Patch for Painless Treatment of Diabetes?

A team from the University of North Carolina has been the first to demonstrate the effectiveness of a synthetic glucose-responsive insulin delivery device that responds to a hypoxia trigger. The device, which uses a painless microneedle-array patch, contains glucose-responsive vesicles that are loaded with insulin and glucose oxidase.

A local hypoxic microenvironment caused by the enzymatic oxidation of glucose in the hyperglycemic state causes such vesicles to be self-assembled and dissociated, with a resultant release of insulin. This patch effectively regulated blood glucose in a mouse model of clinically-induced Type 1 diabetes.
