摘要： A bio-optic gas-imaging system (sniff-cam) with enzyme immobilized mesh demonstrates a spatiotemporal gasimaging for human volatiles (i.e., ethanol, acetaldehyde, etc. after drinking). A bio-fluorometric technique was applied to improve the sensitivity of the gas visualization system. The bio-fluorometric sniff-cam for ethanol was constructed with alcohol dehydrogenase (ADH) immobilized mesh and the NADH imaging unit (UV-LED array & highly sensitive CMOS), thus imaging human ethanol in the gas phase not only exhaled air but also transcutaneous vapor after drinking. The sniffer system would be useful for detecting the volatile biomarkers.
