Andraka’s diagnostic breakthrough is a humble piece of filter paper, except that it is dipped in a solution of carbon nanotubes, which are hollow cylinders with walls the thickness of a single atom, coated with a specific antibody designed to bind with the virus or protein you’re looking for. Andraka’s key insight is that there are noticeable changes in the electrical conductivity of the nanotubes when the distances between them changes. When the antibodies on the surface of the nanotubes come in contact with a target protein, the proteins bind to the tubes and spread them apart a tiny bit. That shift in the spaces between tubes can be detected by an electrical meter. Andraka used a $50 meter from the Home Depot to do the trick but, he says, doctors can just as easily insert his test-strips into the kinds of devices used by millions of diabetics around the world.
