HWGs have successfully been applied to a wide variety of gas-sensing applications [44-52]. Micheels et al. [46] coupled a coiled MIR HWG to a FT-IR spectrometer measuring VOCs in the headspace of water samples. Yang et al. [47,48] partitioned organics from water or the headspace above a soil sample into the coating of a HWG. The waveguide was then inserted into the sample compartment of the FT-IR.

The unique structure and electronic properties of CNTs provide a tremendous potential for construction of CNTs and MOX hybrid materials in the field of gas-sensing applications. Advantages for mixing CNTs in metal oxides for gas sensors are the reduction of operating temperature and enhancement of sensitivity and selectivity due to the amplification effects of p-n heterojunctions with the gas reaction, formation of nanochannels for gas diffusion, high specific surface area, and increase of charge carrier on the surface. As a result of these advantages, the hybrid CNT/metal oxide gas sensor may be used instead of the popular commercial metal oxide gas sensors (such as TGS gas sensors) in the near future.

Solid polymer electrolytes have been prepared from highly plasticized polymers. Early success with an oxygen electrode was demonstrated with several of the first systems developed. Again high silver deposition rates and excessive volatility prevented practical application of most of these. Finally, a polymer-plasticizer system showing adequate sensitivity and stability for application in some gas-sensing applications was developed. 

This synthetic method was a simple and reproducible way to produce well-controlled composite metal- or metal-oxide-containing silica nanomaterials displaying interesting catalytic properties for gas-sensing applications. This study demonstrated that a single approach, deposition of a catalyst suspended in a liquid, may allow the sensitivity of gas sensors to be modulated it also showed that the nature of the material employed was critical for obtaining reproducible results.
