Small wonders: miniature molecular medical monitors.

I'm Bob Karson with "The Discovery Files" -- new advances in science and engineering from the National Science Foundation

Remember the 1966 film, "Fantastic Voyage"? Scientists shrink down a sub and crew, and send it on a journey inside the human body.

Now researchers have found a method to monitor biological functions in much the same way, by implanting tiny molecular structures called nanotubes into the body.

Soon, diabetics may be able to continually monitor blood glucose levels without ever having to draw blood.

The day could come when biomarkers for hundreds of diseases will be revealed by a monitor smaller than an eyelash. It's all part of a new area of research called nanotechnology -- manipulating matter at the molecular level to create a whole range of revolutionary technologies -- for medicine, electronics, the environment, manufacturing and more. Sometimes the biggest innovations come in very small packages.

"The Discovery Files" covers projects funded by the government's National Science Foundation. Federally-sponsored research brought to you by ... you! Learn more at
