New Material Could Improve Safety for First Responders to Chemical Hazards

April 29, 2011

porous photonic crystal microsensor particles Carbon nanofibers with the same chemical properties as the activated charcoal used in respirators have a similar ability to absorb chemical pollutants. Their photonic structure means that they will change color as pollutants accumulate, a warning that the filter canister has lost effectiveness. Researchers describe how they made the microsensors and demonstrate their ability to detect volatile organic compounds in a recent issue of Advanced Materials. Full Story

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
