These nanoparticles designed for Type 1 diabetes would potentially replace constant monitoring of blood sugar levels and the injection of insulin. People with diabetes basically has to prick their fingers everyday to check their glucose level and inject inulin if the blood glucose level is too high to break down the sugar in the body. Fortunately, these particles could automatically sense glucose levels and secrete the right amount of insulin, replacing the pancreatic islet cells. Recently, scientists figured out a new insulin-delivery system which acts as an artificial pancreas, automatically detecting and releasing insulin. The system consists of injecting a gel-like substance mixed with nanoparticles that hold the particle together. Furthermore, the researchers are now trying to modify the particles so they can respond to changes in glucose levels faster, at the speed of pancreas islet cells. (D4)
