Lung Cancer Breath Test Of The Electronic Nose Design

This work mainly compared the VOCs in lung cancer patients breath and in normal human breath to determine the correlation between lung cancer and the marker VOCs. Following, we developed an electronic nose adopting advanced technology which combined capillary column to separate VOCs according their different retention time and surface acoustic wave sensor coating with polymer film to detect the qualities of those VOCs.In my article, lung cancer situation, breath detection principle, feasibility of electronic nose adopting breath detection, and the principles of SPME & GC have been particularly introduced. And initially certified the correlation between lung cancer and the marker VOCs by detecting lung cancer patients breath, normal human breath, and lung problem patients by solid phase microextraction(SPME) and gas chromatography(GC) system. And we mainly finished breath detection electronic nose system, including surface acoustic wave sensor design, film coating design, and hardware & software design for future detection marker VOCs in lung cancer breath by electronic nose.
