Researchers from the University of North Carolina at Chapel Hill, North Carolina State University and Changchun Institute of Applied Chemistry at the Chinese Academy of Sciences have developed a skin patch that measures blood glucose levels and releases insulin when levels climb too high. The team’s work testing the patch in mice was published earlier this month in ACS Nano.
People suffering with Type I diabetes don’t make insulin, while those with Type II can’t use insulin effectively. Both groups of patients are tasked with monitoring their blood sugar regularly using finger prick tests. Some patients inject themselves with insulin when their blood sugar fall to dangerous levels. But, even if a patient is closely monitoring their readings, their blood glucose levels can get out of control.
