NASA Nanotechnology-Based Biosensor Helps Detect Biohazards


(Wireless News Via Acquire Media NewsEdge)
NASA reported that it has developed a nanotechnology-based biosensor
that can detect trace amounts of specific bacteria, viruses and
parasites.

The biosensor will be used to help prevent the spread of potentially
deadly biohazards in water, food and other contaminated sources.

NASA's Ames Research Center at Moffett Field in California licensed the
biosensor technology to Early Warning Inc., Troy, N.Y. Under a
Reimbursable Space Act Agreement, NASA and Early Warning jointly will
develop biosensor enhancements. Initially, the biosensor will be
configured to detect the presence of common and rare strains of
microorganisms associated with water-borne illnesses and fatalities.

"The biosensor makes use of ultra-sensitive carbon nanotubes which can
detect biohazards at very low levels," explained Meyya Meyyappan, chief
scientist for exploration technology and former director of the Center
for Nanotechnology at Ames. "When biohazards are present, the biosensor
generates an electrical signal, which is used to determine the presence
and concentration levels of specific micro-organisms in the sample.
Because of their tiny size, millions of nanotubes can fit on a single
biosensor chip."

Early Warning company officials say food and beverage companies, water
agencies, industrial plants, hospitals and airlines could use the
biosensor to prevent outbreaks of illnesses caused by pathogens -
without needing a laboratory or technicians.



"Biohazard outbreaks from pathogens and infectious diseases occur every
day in the U.S. and throughout the world," said Neil Gordon, president
of Early Warning. "The key to preventing major outbreaks is frequent
and comprehensive testing for each suspected pathogen, as most
occurrences of pathogens are not detected until after people get sick
or die. Biohazards can enter the water supply and food chain from a
number of sources which are very difficult to uncover.

"Ambitious space missions have produced some of the world's most
creative technologies by NASA and its industrial partners," said Harry
Partridge, deputy director of the Space Technologies Division at Ames.
"Not only does NASA want these technologies used in space applications,
an equally important objective is the transition of NASA research into
real world products that can benefit our society."
