The graphene-based nanoelectronic sensor measures nitrite in tiny liquid droplets discharged during breathing. Researchers discussed their device in a study<\/a> published last week in the journal Microsystems & Nanoengineering<\/i>.

As a \u201cportable non-invasive approach for measuring indicators of inflammation and oxidative stress in the respiratory tract by quantifying a biomarker in exhaled breath condensate,\u201d the sensor is seen as a potential replacement for other \u201ccurrently available non-invasive methods for diagnosing and monitoring asthma (that are) limited by low sensitivity and the need for expensive and bulky equipment,\u201d according to the authors.

Mehdi Javanmard, an assistant professor in the Department of Electrical and Computer Engineering at Rutgers University-New Brunswick, contends that the handheld tool can monitor nitrite and enable better diagnoses as well as more appropriate treatments and management of asthma and other respiratory diseases, while in the process preventing costly hospitalizations and even deaths.

\u201cThis is the first critical step in basically miniaturizing an electrochemical sensor that accurately measures nitrite in exhaled breath condensate,\u201d says Javanmard. \u201cWe now have essentially a chip that is the size of my finger.\u201d

Ultimately, he says the goal is to develop a wearable system that asthmatic patients and others with respiratory conditions can wear on their wrist or around their neck and blow into to get a reading for the possible extent of lung inflammation.

\u201cOur plan is to have the storage of the data and the analysis performed on a smartphone, and then to have the information uploaded to the cloud,\u201d adds Javanmard, who believes the system could be commercially available within five years.

\u201cTo get a medical device on the market, we will have to go through FDA approval,\u201d he concludes. \u201cHowever, to just build the technology itself and be in a position where we can start doing clinical trials, that\u2019s on the order of less than a year away. The real bottleneck is the time it takes to go through regulatory hurdles.\u201d

At the same time, Javanmard says the Rutgers research team is still looking for a commercial partner such as a medical device manufacturer with which they can collaborate on the project.","saveContent":"Rutgers University researchers have created a sensor that detects nitrite, an important inflammatory biomarker in the inner lining of the respiratory airway, which could lead to earlier detection of asthma attacks and other respiratory conditions.
