Newly developed nanotech sensors may help test efficacy of cancer drugs


NEW YORK One day physicians may be able to determine the effectiveness of cancer drugs using tiny sensors.

According to a report published Sunday in the journal Nature Nanotechnology, researchers at the Massachusetts Institute of Technology developed nanotechnology sensors made of carbon nanotubes that can detect toxins and drugs inside living cells.

The sensors are coated with DNA and made to give off fluorescent light to make them detectable after injection into cells.
