Pinpoint Germs in Eight Minutes

posted on July 5, 2002

Germs …they can run but can't hide.

Cornell University scientists are developing a handheld sensor to quickly pinpoint poisonous germs in food and drinks.

The device attaches antibodies to the outside of microscopic fat bubbles on a test strip. A sample moving up the strip attaches to the antibodies and turns red if E. coli is present.

A negative sample would not change color.

The device will detect potentially lethal microbes in eight minutes.
