Just as NevadaNano’s Self-Sensing ArrayTM (SSA) technology analyzes trace vapors given off by E. coli and Salmonella occurring in the food chain, these unique devices will also analyze breath samples for biomarkers for cancer and other diseases.
Cancerous cells produce marker molecules that are released into the bloodstream and then via the blood capillaries in the lungs. From there, they find their way into human breath and, when exhaled, can be sensed by the SSA in our sensor modules where these same marker molecules are detected. Lung cancer, for instance, produces a mixture of alkanes and benzene derivatives.
Diseases such as diabetes, liver cirrhosis, and renal failure each have their own chemical signature. Diabetes has long been associated with a characteristic “sweet acetone” smell on human breath, and can be detected by the SSA through the sensing of abnormal concentrations of acetone as a marker.
