Sweet Glow: Nanotube sensor brightens path to glucose detection
Biomedical engineers have developed a new kind of glucose sensor, based on carbon nanotubes, that could free people with diabetes from the daily pinprick tests now required for monitoring blood sugar concentrations.

Michael S. Strano and his colleagues at the University of Illinois at Urbana–Champaign designed the new sensor. Although the first medical target is glucose sensing, Strano says the same basic design is widely applicable for such analytical tasks as detecting genes and proteins associated with diseases.
