Electronic Nose to Sniff Out Toxins Developed
Support for the development and application of this electronic nose comes from the National Institute of Environmental Health Sciences, part of the National Institutes of Health.
Once fully developed, the sensor could be useful in detecting high exposures to toxic industrial chemicals that pose serious health risks in the workplace or through accidental exposure.
While physicists have radiation badges to protect them in the workplace, chemists and workers who handle chemicals do not have equivalent devices to monitor their exposure to potentially toxic chemicals.
The investigators hope to be able to market the wearable sensor within a few years.
"The project fits into the overall goal of a component of the GEI Exposure Biology Program that the NIEHS has the lead on, which is to develop technologies to monitor and better understand how environmental exposures affect disease risk," said NIEHS Director Linda Birnbaum.
"This paper brings us one step closer to having a small wearable sensor that can detect multiple airborne toxins," she added.
Kenneth S. Suslick, the M.T. Schmidt Professor of Chemistry at the University of Illinois at Urbana-Champaign, and his colleagues have created what they refer to as an optoelectronic nose, an artificial nose for the detection of toxic industrial chemicals (TICs) that is simple, fast, inexpensive, and works by visualizing colors.
