Pollutants, Disease And Biological Weapons Detected By Tiny "Lab-On-A-Chip"

For centuries, animals have been our first line of defense against toxins. A canary in a coalmine served as a living monitor for poisonous gases. Scientists used fish to test for contaminants in our water. Even with modern advances, though, it can take days to detect a fatal chemical or organism. Until now. Working in the miniaturized world of nanotechnology, Tel Aviv University researchers have made an enormous - and humane - leap forward in the detection of pollutants. Read more ...
