A nanotech-laser treatment that can destroy cancer cells without damaging healthy tissue has been developed by Stanford University scientists.
The scientists placed a solution of carbon nanotubes -- synthetic rods that are only half the width of a DNA molecule -- under an infrared laser beam.
The laser beam heated the carbon nanotube solution to about 158 degrees Fahrenheit within two minutes.
When nanotubes were placed inside cells and radiated by the laser beam, the cells were quickly destroyed by the heat. However, cells that did not
contain any nanotubes were not affected by the laser beam. -
