Fluctuation-enhanced sensing of bacterium odors

摘要: The goal of this paper is to explore the possibility detect and identify bacteria by sensing their odor via fluctuation-enhanced with commercial Taguchi sensors. fluctuations electrical resistance during exposure different bacterial odors, Escherichia coli anthrax-surrogate Bacillus subtilis, have been measured analyzed. In present study, simplest method, measurement analysis power density spectra was used. sensors were run in normal-heated sampling-and-hold working modes, respectively. results indicate that used these modes are effective tools bacterium detection identification even when they utilizing only spectrum stochastic sensor signal.
