![Illustration shows how a tiny needle full of carbon nanotubes could work as glucose sensor.](https://webarchive.library.unt.edu/eot2008/20081107153145im_/http://www.nsf.gov/news/mmg/media/images/sensor_new_f.jpg) |
Tiny, implantable devices filled with carbon nanotubes may someday help diabetics monitor glucose levels without drawing blood. Researchers hope that nanotubes--thanks to their strength, conductivity and light-emitting properties--will lend themselves to a range of similar "biosensing" applications.
