Matt Peckham discusses a technology that may help diabetics avoid the majority of their frequent insulin injections:
Say you’re diabetic: Instead of having to inject yourself with insulin multiple times a day, imagine only having to do it once a week. Crazy, right? And instead of your syringe harboring glucose-regulating insulin, imagine it filled with nanoscopic particles you fire into your bloodstream — particles capable of detecting when your body’s blood sugar levels rise and releasing insulin accordingly.
Thanks to research conducted at North Carolina State University, the University of North Carolina at Chapel Hill, the Massachusetts Institute of Technology and Children’s Hospital Boston, what sounds like a Kurzweilian science fiction fantasy may soon be reality for the estimated 25.8 million children and adults in the U.S. alone — 8.3% of the population, according to the American Diabetes Association – with high blood sugar (and 366 million in all worldwide).
“We’ve created a ‘smart’ system that is injected into the body and responds to changes in blood sugar by releasing insulin, effectively controlling blood-sugar levels,” says NC State University biomedical engineering assistant professor Dr. Zhen Gu, the lead author of a paper describing the work (via NC State news). ”We’ve tested the technology in mice, and one injection was able to maintain blood sugar levels in the normal range for up to 10 days.”
