Schematic for 'DNA-Based Testing for Environmental Contamination'
A schematic of DNA aptamers incorporated into an electrochemical sensor device. A team from the U.S. Army Engineer Research and Development Center’s Environmental Laboratory invented “DNA-Based Testing for Environmental Contamination,” a process that earned a patent in February 2020. The invention provides synthetic DNA aptamers that bind a target explosive to allow detection of that explosive. (U.S. Army Corps of Engineers photo)
