Uses for Healthcare & Life Sciences

From devices that monitor exercise, sleep, and health information, to sensors that let our doctors know if we’re taking our medicine properly, the Internet of Things is poised to dramatically change the way we stay healthy. NevadaNano’s Molecular Property Spectrometer™ (MPS™) technology can be used to help identify and diagnose health conditions, as well as assess personal hygiene and metabolic functions such as exercise and stress levels.

All living organisms give off unique mixtures of exhaled gases as part of their metabolism. These distinct metabolite signatures can include unburned hydrocarbons, alcohols, ammonia, oxygen, carbon dioxide, short-chain fatty acids, aldehydes, and other breakdown products of amino acids. These characteristic “odors” can be detected and differentiated using pattern recognition techniques in order to identify bacterial strains and chemical signatures. This approach has been demonstrated for diagnosis of bacterial infections by sampling urine vapor, detection of pulmonary infections, prediction of bacterial type and culture growth phase, classification of grains, and detection and identification of a range of microorganisms.

Digital scent enabled by MPS™ will help us monitor our health, provide early detection of diseases and give us longer, healthier lives.

Chemicals: ammonia, oxygen, carbon dioxide, aldehydes, ethanol, alcohol

Additionally, thousands of chemicals have been identified in exhaled human breath. Many of these are linked to certain health conditions, environmental exposures, and metabolic functions; characterizing the chemical makeup of breath can reveal a great deal of health-related information. For example, cancerous cells produce marker molecules that are released into the bloodstream and then the lungs, via the blood capillaries. From there, they find their way into human breath. Lung cancer produces a mixture of alkanes and benzene derivatives; diabetes has long been associated with a characteristic “sweet” acetone smell on human breath. Liver cirrhosis and renal failure have characteristic smells as well. As such, multiple medical breath tests have already been approved by the U.S. Food and Drug Administration (FDA).
