Abstract
Exhaled breath analysis is in the development stage and has many potential advantages over conventional laboratory tests. Real-time exhaled breath analyzers can be based on a variety of technologies such as gas chromatography, mass spectrometry, optical measurements, electrochemical sensors, and chemical sensors. The chemical sensors can be based on the nanothin films as gas-sensitive layers. The development of nanoscale materials presents new unlimited possibilities for gas-sensing applications, including exhaled breath analysis. The possibility of replacing classical glucose-level testing using blood samples with noninvasive exhaled breath analysis seems to be particularly attractive for diabetes patients who need to control their glucose concentrations several times per day. This need has created huge market expectations regarding portable exhaled breath analysis based on cheap and fast gas sensors, including metal oxide-based gas sensors. This chapter describes the recently published results on exhaled acetone measurements, including a discussion on the possibilities and limitations for rapid launching into the market. One of the parameters that has been used to compare the various results is response level, which is generally defined as the electrical resistance ratio Ra/Rg or Rg/Ra, where Ra and Rg are electrical resistances measured under exposure to air and target gas, respectively.
