Using a material of 120-nm polymer beads containing a fluorescent dye and glucose specific sensing molecules, Heather Clark, at the Draper Laboratory (Cambridge, MA) has developed a skin-implanted serum glucose monitor that glows under an infrared light to indicate an insulin need. Fluorescence level indicates glucose level.  Unlike tattoo dye, this device would be replaced as skin sloughs off, but easily could be replaced.  So far, this has only been tested in laboratory mice.  MORE
