has developed a biosensor that will be used to help prevent the spread of biohazards in water, food and other contaminated sources. The sensor works by detecting trace amounts of bacteria, viruses and parasites.

‘The biosensor makes use of ultra-sensitive carbon nanotubes which can detect biohazards at very low levels,’ said Meyya Meyyappan, chief scientist for exploration technology and former director of the Center for Nanotechnology at
Early Warning company officials said food and drink companies, water utilities, industrial plants, hospitals and airlines could use the biosensor to prevent outbreaks of illnesses caused by pathogens. The company expects to launch its water-testing products in late 2008.
