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®, 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 whereas 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, reusable, and portable
sensor to detect harmful, and occasionally weaponized, pathogens. This award-winning team of
biochemists, electrochemists, materials scientists, and microsystems experts will develop bold new
products to save lives,” said Neil Kane, ADT’s president.
The worldwide market for chemical and biological sensors is estimated by several market research firms
to be greater than $10 billion. The need to protect people from environmental and deliberate threats is
“Smooth, electrically conducting diamond film has many potential advantages for biosensors. By using
MEMS (micro electrical mechanical systems) technology, we can miniaturize the devices making it
economically feasible for people to carry a sensor in their wallet or as a piece of jewelry which would
allow them, for example, to determine if water is safe to drink. In the case of military personnel or first
responders, detectors could be integrated into uniforms or personal protective equipment," said John
Carlisle, ADT’s chief technical officer.
Professor Robert J. Hamers, the Irving Shain Professor of Chemistry and Chemistry Department Chair at
UW will be spearheading the project’s development of linker chemistry and biomolecular capture agents
to selectively detect various types of bacteria. UIUC Professors William King, Kritzer Faculty Scholar,
Department of Mechanical Science and Engineering, and Rashid Bashir, Bliss Professor, Department of
Electrical and Computer Engineering & Bioengineering and Director of the UIUC Micro and
Nanotechnology Laboratory, will design and characterize diamond MEMS structures (i.e., cantilever
arrays) that will integrate electrical, mechanical, and thermal functionalities together to detect the
presence of bacterial threats in real-time.
