Researchers test administering medication using nanotechnology, gold

NEW YORK Researchers have developed a way to use tiny particles of gold to control the administration of drugs for diseases such as cancer, according to a study published in the journal ACS Nano.

The researchers, at the Massachusetts Institute of Technology, created a device that shines infrared light on particles of gold coated with medicine.

The particles vary in size, causing them to melt at different rates depending on the intensity of the light.

The researchers said the device would allow medicine to target specific areas of the body at specific rates, thus minimizing damage to healthy tissue.
