Enhancement Acetone Sensing Performances of SnO_2 Nanorod Arrays By Decorating Noble Metal Catalysts

摘要

Breath analysis using gas chromatography (GC) to identify more than 200 compounds in the human breath came into practice in the 1970s. Endogenous compounds such as inorganic gases (NO, CO) and VOCs (acetone, ethanol, ammonia, ethane and pentane) in the human breath serve as a biomarker for several diseases. Breath acetone is related to diabetes, fasting, fat metabolism, and other numerous diseases.
