NEW BRUNSWICK, N.J. – Scientists at Rutgers University have developed a grapheme-based sensor that could predict an asthma attack.
The miniaturized electrochemical sensor accurately measures exhaled breath condensate using reduced grapheme oxide, which resists corrosion, has superior electrical properties and accurately detects biomarkers.
“Nitrite level in breath condensate is a promising biomarker for inflammation in the respiratory tract,” said Clifford Weisel, professor at Rutgers’ Environmental and Occupational Health Sciences Institute and co-author of a recently published study describing the invention.
“Having a rapid, easy method to measure it can help an asthmatic determine if air pollutants are affecting them so they can better manage use of medication and physical activity.”
The next step for the researchers is to develop a portable, wearable system, which could be commercially available in five years, said Mehdi Javanmard, a researcher on the team, in a statement.
“Our vision is to develop a device that someone with asthma or another respiratory disease can wear around their neck or on their wrist and blow into it periodically to predict the onset of an asthma attack or other problems,” he said. “It advances the field of personalized and precision medicine.”
