Genetically Engineered Bacteria to Measure Water Quality
March 20th, 2009 by Amiel Blajchman
Researchers at Tel Aviv University have developed a laboratory the size of a microchip that can be used to measure water quality. Using genetically engineered bacteria that light up when in contact with pre-determined pollutants, this water quality lab will detect and communicate “contact” with monitoring systems. It’s a nano sized version of the robot fish that we recently looked at.
“We’ve developed a platform – essentially a micro-sized, quarter-inch square ‘lab’ – employing genetically engineered bacteria that light up when presented with a stressor in water,” says team lead Professor Shacham-Diamand.
Other potential uses of this micro-scale monitoring system include almost any biological process that can affect or be affected by purpose-designed bacteria, including stem cell and cancer investigations. Even the United States Department of Defense Projects Agency (DARPA) is interested, as these nanotechnology labs may become a defense against future biological warfare attacks.
