Researchers say this technology may be 10 years away, but it's coming.
A high tech cousin of your favorite CD to perform medical tests instead of songs. The physics folks at Purdue University are pioneering what they call Bio-CDs.
The uniquely designed surface of the analog CD is covered with tiny pits like test tubes. Each micro-test tube contains an antigen that will bind to a specific protein.
When a laser beam reads the CD, it looks for high concentrations of certain proteins in those tiny test tubes, indicating the presence of a possible disease or condition.
