Student team's glucose sensor uses DNA instead of chemicals

People with diabetes may one day have a less expensive resource for monitoring their blood glucose levels, if research by a group of Missouri University of Science and Technology students becomes reality.

Members of the Missouri S&T chapter of iGEM - the International Genetically Engineered Machine Foundation - recently devised a biological system that uses segments of DNA embedded in bacteria to detect glucose. The students believe their development could lead to a new type of test strip for diabetics.
