Do butterflies hold the key to the next generation of chemical sensors? DARPA apparently thinks they might, and it's just awarded GE a $6.3 million grant to further develop a project that the company's research division began three years ago. That project was sparked by the discovery that the nanostructures from the wing scales of butterflies have acute chemical sensing properties, which GE has since been working to replicate in a sensing platform that could instantly detect a wide variety of chemical threats. What's more, GE says that it's sensors could eventually be made in "very small sizes, with low production costs," which would let them be used for everything from emissions monitoring at power plants to food and beverage safety monitoring at home. Full press release is after the break.
GE Awarded $6.3 Million DARPA Grant to Develop New Bio-inspired Sensors
Replicating nanostructures from the wings of Morpho butterflies, GE's sensors would enable highly selective, near-instantaneous detection of chemical threats
GE's sensing platform could create other industrial and healthcare applications, including emissions monitoring at power plants, water purification and food safety testing and breath analysis for disease detection

NISKAYUNA, N.Y.--(EON: Enhanced Online News)--Scientists at GE Global Research, GE's technology development arm, in collaboration with Air Force Research Laboratory, State University at Albany, and University of Exeter, have received a four-year, $6.3 million award from the Defense Advanced Research Projects Agency (DARPA) to develop new bio-inspired nanostructured sensors that would enable faster, more selective detection of dangerous warfare agents and explosives.
"GE's bio-inspired sensing platform could dramatically increase sensitivity, speed and accuracy for detecting dangerous chemical threats. All of these factors are critical, not only from the standpoint of preventing exposure, but in monitoring an effective medical response if necessary to deal with such threats."
Three years ago, GE scientists discovered that nanostructures from wing scales of butterflies exhibited acute chemical sensing properties. Since then, GE scientists have been developing a dynamic, new sensing platform that replicates these unique properties. Recognizing the potential of GE's sensing technologies for improving homeland protection, DARPA is supporting further research.
Radislav Potyrailo, a principal scientist at GE Global Research and principal investigator, said, "GE's bio-inspired sensing platform could dramatically increase sensitivity, speed and accuracy for detecting dangerous chemical threats. All of these factors are critical, not only from the standpoint of preventing exposure, but in monitoring an effective medical response if necessary to deal with such threats."
Potyrailo noted that GE's sensors can be made in very small sizes, with low production costs. This would allow large volumes of these sensors to be readily produced and deployed wherever needed. Unique sensing properties, combined with the size and production advantages offered by GE's bio-inspired sensors, could enable an array of other important industrial and healthcare applications, including:
Emissions monitoring at power plants
Food and beverage safety monitoring
Water purification testing for home, environmental and industrial applications
Breath analysis for disease detection
Wound healing assessment
Potyrailo said, "Now, more than ever, sensors are being used to collect data on gas concentrations and to deliver important information about air conditions in localized regions or over large distributed areas. This information can range from warning of impending chemical or health threats to more precisely measuring air quality at a power plant. The unique sensing properties of GE's bio-inspired sensors provide an opportunity to improve the quality of this sensing data and the ability to collect this data at previously unavailable levels of detail."
DARPA Program Manager Viktoria Greanya, Ph.D., said: "We have been greatly inspired by examples of naturally occurring optical structures whose properties arise from an intricate morphology. For example, the brilliant colors seen in butterfly wings, beetle carapaces, and peacock feathers are due in large part to their complex structure, not simply their color. DARPA's goal in this program is to harness the best of nature's own photonic structures and use advances in materials technology to create controllable photonic devices at visible and near-infrared wavelengths."
For the DARPA project, GE has assembled a world-class team of collaborators who are recognized experts in their fields. They include: Dr. Helen Ghiradella, from State University at Albany, an expert on the biology of structural color; Dr. Peter Vukusic, from the University of Exeter, an expert on the physics of structural color; Dr. Rajesh Naik, from the Air Force Research Laboratory, with a strong background in bio-inspired functional materials and surface functionalization; and Dr. John Hartley, also from State University at Albany, specializing in advanced lithographic nanofabrication. These team members will complement GE's strong multidisciplinary team of analytical chemists, material scientists, polymer chemists, optical engineers and nanofabrication engineers who are contributing to development of this new platform.

Butterflies: not as innocent as they appear. Behind those beautiful wings are microcomputers that take readings on everything in your home. Once they've found your weak spot, consider yourself SCREWED.
On-topic: What the hell does GE need grants for?
@Diggler Like any American corporation, they probably got hit hard in the recession. Research and development tends to suffer when a companies are in an unstable market.
The Butterfly Effect... Interesting, very interesting.
@androidfan1 6 minutes late there, bud. And I managed to write a whole freakin' paragraph.
Wait, why the hell am I feeding trolls?
@androidfan1 ...into oblivion!
This world is so complex, irs amazing.
Homegrown exploits. I'll guess that the Roswell alien tech: e.g. nano-carbon fibers, miniturized integrated circuits on silicon, lazers, fiber optic information transport, night vision tech etc. have benn fully leveraged. Time to look inward...
I'm sorry is it just me or does anybody else think it is insane for our broke government to piss another $6.3 million dollars on something so non-essential? If it is such a great idea where is the private sector dollars for such folly? Quoting Susan Pouter: "Stop the insanity"
@tmogeek
The problem is USA relies on military strength to engage in terror both home and abroad and to enforce that police state. You'll find 99% of tech articles on Engadget involving the USA involve the military and the government.
Of course the tax-payers are getting fleeced, big time. That's without going into bail-outs. This is a drop in the ocean, really.
The country goes deeper into debt (and to war) on the backs of the tax-payers, but they don't care because it's these few at the top benefiting from it all and profiting stupendously, while the rich continue getting bailed-out.
@tmogeek
So should we just quit doing all "non-essential" basic research? Maybe close down all the Universities and send the scientists packing?
GE saw fit to invest in the initial R&D money and DARPA saw potential use for that technology.
It is unfortunate that we tend to invest in military technology more than civilian but technology is what drives the economy and will be the only way this country can keep from becoming second rate.
You wouldn't be hanging out on Engadget if you didn't believe that.
They should just make genetically enhanced Butterflies that text back home when they detect a threat!
Oh well that would barely work in the cities
