We constructed an imaging system to measure the concentration of acetone gas by acetone
reduction using secondary alcohol dehydrogenase (S-ADH). Reduced nicotinamide …

Trace acetone contained in the human-derived vapor is a potential indicator of lipid
metabolisms. Exhaled breath and skin gas contain various kinds of volatile chemicals. Thus …

Several volatile organic compounds (VOCs) are released from human breath or skin. Like
chemical substances in blood or urine, some of these vapors can provide valuable …

A highly sensitive acetone bio-sniffer (biochemical gas sensor) for assessment of lipid
metabolism utilizing reverse reaction of secondary alcohol dehydrogenase was fabricated …

A fluorometric acetone biosniffer (biochemical gas sensor) for assessment of lipid
metabolism utilizing reverse reaction of secondary alcohol dehydrogenase was constructed …

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 …

Measurement of acetone in human breath samples has been previously shown to provide
significant non-invasive diagnostic insight into the control of a patient's diabetic condition. In …

Acetone contained in our exhaled breath is a metabolic product of the breakdown of body fat
and is expected to be a good indicator of fat-burning. Typically, gas chromatography or mass …

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 …

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