(Inside Science TV) – Everything from food, to air to water runs the risk of becoming contaminated. Now, chemists at the Lawrence Livermore National Laboratory in California have developed a technology that can detect and track dangerous particles in food and in the air.
“The DNA in the material can be used to identify those particles," said George Farquar, a chemist at Lawrence Livermore National Laboratory.
With the technology, called DNA Trax, researchers create tiny sugar-based particles and label them with a unique DNA signature. The particles can be sprayed onto food or released into the air to track the source of contaminants.
