Screen for Disease with JUST a FEW breaths

Rapid and non-invasive disease screening at the point of care


Imagine walking into a doctor’s office or mobile clinic for a disease screening, breathing a few breaths into a breath-collection bag, and getting your results within ten minutes. This is the promise of Exhalent Diagnostics’ revolutionary disease-screening platform: Rapid and non-invasive disease diagnosis at the point-of-care, or wherever you need it, to improve treatment outcomes, limit the spread of disease, and save lives.

The Technology

Exhalent Diagnostics’ breakthrough sensors are made of self-organizing titanium dioxide nanotube arrays. The sensors can be structured—by varying the length, diameter, and wall thickness of the nanotubes—to detect specific molecules, including biomarkers associated with a variety of diseases. When target molecules are present, they react with the nanotubes and create a measurable electrical response.



Biomarkers, measurable indicators of a biological process, can be used to assess the risk or progression of a disease. Volatile organic compounds (VOCs) in breath can act as biomarkers for a variety of diseases, including cancers, diabetes, and infectious diseases. But, measuring VOCs in breath is difficult. VOCs are often present in extremely small quantities and they degrade very quickly. The equipment required to sense them is expensive and cumbersome, making clinical use infeasible. Indeed, there is to date no clinically approved application to diagnose disease using breath-based biomarkers. Our revolutionary sensing technology will change that.


In lab tests published in peer-reviewed scientific journals [1,2,3,4,5], as well as in an unpublished 600 patient field study, our sensors successfully detect four unique breath-based biomarkers produced by an active tuberculosis (TB) infection. After validating our platform by developing a screening test for TB, we intend to pursue other important potential applications, including promising tests for colorectal cancer and pneumonia, among others.

If you are interested in using our sensor to detect other biomarkers or molecules, please contact us.


Our device is easy-to-use and designed so that healthcare workers—ranging from physicians to medical assistants—can easily administer screening tests at the point-of-care or wherever needed. The process is simple: A patient fills a breath collection bag with a few exhaled breaths, and the care-giver connects the bag to a sensor unit. A pump automatically passes the exhaled breath across the sensor. Target biomarkers for a disease, if present, bind to the sensor and generate a measurable electrical response, which is then communicated to a tablet or smartphone. Our app, using a proprietary algorithm, provides results in less than ten minutes. The breath bag with the sensor is then discarded and a new one used for the next test.

Jason cares about improving the lives of those around him, although he does it through entrepreneurship rather than attending to individual patients. While in medical school, he saw firsthand the impact of innovative technologies on the lives of his patients. After medical school, he decided to combine his knowledge of medicine with his skills and experience in business to help startups commercialize these technologies. He brings his expertise—including interfacing with medical care providers, developing relationships with key partners, managing field studies and clinical trials, and implementing innovative business models—to Exhalent Diagnostics. Jason received his M.D. from the University of Utah and his M.B.A. from the University of Notre Dame.
