In this chapter, an overview on fiber-optic chemical and biosensors is presented focusing on transducers and transduction mechanisms, sensor design, sensor development and processing, and sensor characterization and optimization. A few examples are presented on chemical vapor detection and biosensing applications. At the end of the chapter, the theory and application of the newly developed detection technique, which is called the SIM technique, is presented.

This paper has dealt exclusively with SAW sensors that exploit the mass sensitivity of the device to achieve chemical vapor detection. Schemes to exploit the SAW sensitivity to coating conductance changes (17) or elastic modulus changes should afford new opportunities for imaginative chemical vapor sensor designs. Finally, the field of liquid phase chemical analysis may also yield to surface acoustic wave devices that utilize plate waves and horizontally polarized shear waves to minimize acoustic losses in the liquid (18). 

The hydrogen bond acidic polycarbosilane HC was examined as a sorbent coating for chemical vapor detection by ATR-FTIR. For optimal sensitivity, ATR-FTIR instruments must have physical contact between a sufficient mass of...
