A non-invasive treatment for diabetes monitoring and drug delivery has been developed by South Korean researchers at The Institute for Basic Science (IBS) Center for Nanoparticle Research located in Seoul, South Korea. The device, a graphene-based patch, uses a hybrid of gold-doped graphene and a serpentine gold mesh to measure pH (blood acidity level) and temperature by measuring the amount of glucose in sweat. If abnormally high levels of
