Near Infrared Nanoparticles Shine A Bright Light On Cancer

Friday, September 26, 2008 - 19:21 in Physics & Chemistry

A new imaging method for breast cancer has been developed. More effective early detection of diseases is one of the promises of nanotechnology. Current imaging methods, such as x-rays and magnetic resonance imaging, are limited in the size of tumors they can detect, the depth they can penetrate the body, and by their potential side effects. Another promising imaging technique, near infrared bioimaging, is a noninvasive, painless, and non-ionizing form of radiation that operates at wavelengths just above that of visible light.
