Various volatile organic compounds can be found in human transpiration, breath and body
odor. In this paper, a novel two-dimensional fluorometric imaging system, known as a “sniffer …

Measuring the volatile organic compounds (VOCs) released from a human is a promising
method for noninvasive disease screening and metabolism assessment. Selectively imaging …

Understanding concentration distributions, release sites, and release dynamics of volatile
organic compounds (VOCs) from the human is expected to lead to methods for noninvasive …

We developed a gas-imaging system (sniff-cam) for gaseous ethanol (EtOH) with improved
sensitivity. The sniff-cam was applied to measure the extremely low concentration …

Skin gas that contains volatile metabolites (volatilome) is emanated continuously and is thus
expected to be suitable for non-invasive monitoring. The aim of this study was to investigate …

A 2-dimensional imaging system was constructed and applied in measurements of gaseous
ethanol emissions from the human palm. This imaging system measures gaseous ethanol …

A non-invasive breath gaseous ethanol imaging system with an exhaled breath flow rate
control has been developed. The system offers straight-forward, rapid, and painless …

In this study, a highly sensitive and selective biochemical gas sensor (bio-sniffer) and real-
time monitoring system with skin gas cell was constructed for the determination of ethanol …

Non-invasive measurement of volatile organic compounds (VOCs) emitted from living
organisms is a powerful technique for diagnosing health conditions or diseases in humans …

Human-borne acetone is a potent marker of lipid metabolism. Here, an enzyme
immobilization method for secondary alcohol dehydrogenase (S-ADH), which is suitable for …
