Abstract Scope |
The medical science has been aware of the diagnostic potential of the gaseous metabolites emitted from the human body for centuries, however even with the recent technological advances, this potential has not been fully realized. We present here a skin testing device is like a “magic wand” passing over one’s arm that reads the gaseous headspace above the skin for disease, creating the new era for non-invasive personalized medicine. We focus here on an electronic olfaction device based on gas sensing utilizing a small number, just four, of metal-oxide nanowire sensors that are specifically sensitive to the biomarkers of interest (isoprene, ammonia, acetone and NO). We have been testing the device performance using synthetic gas mixtures that simulate the headspace of skin gas emissions. |
