Nanotubes for cancer cure
Published: May 12, 2006
Scientists have found ways to cork the world’s tiniest test tubes, which they want to fill with drugs and inject into patients for the treatment of cancer.
The diameter of the tiniest tubes, scientists have made, are about 80 nanometres or 80-billionth of a metre. Even though they are tiny, each tube can hold about five million drug molecules.
They will seek diseased or cancerous cells, uncork and spill their therapeutic contents in the right place.
“Because they are open at one end it would be like trying to ship wine in a bottle without a cork,” explained scientist Charles Martin, University of Florida. To make chemotherapy hit only the cancerous cells, scientists have spent years experimenting with drug-carrying nanotubes.
