ADT awarded a contract to make diamond biosensors

By Jeremy Ondrey |

Advanced Diamond Technologies Inc. (ADT; Romeoville, Ill.; www.thindiamond.com) announces it has been awarded the first phase of a three-year, $4.8-million contract from the Defense Threat Reduction Agency (DTRA; www.dtra.mil) to develop diamond-based sensors for the realtime detection of water-based chemical and biological agents. The project’s goal is to develop miniature devices to protect first responders during a terrorist event by detecting water-borne pathogens, bacterial agents, and toxins such as E. coli, Listeria, and Salmonella. Project collaborators include the University of Wisconsin-Madison (UW) and the University of Illinois at Urbana-Champaign (UIUC). ADT’s nanostructured diamond, known as UNCD (CE, April 2008, p. 13; www.chemengonline.com/news/3808.html), will be used to make diamond devices that are extremely sensitive detectors of chemical and biological agents. Diamond forms a stable and exceptionally strong bond with biomolecules in water. Other materials immediately degrade and fail. This durability, coupled with ADT’s expertise in the microfabrication of UNCD, will make portable, reusable sensors a reality. “There is an enormous need, both for military and civilian uses, to have a quick,…
