The thin film fiber optic reflective sensor based on palladium catalyzed W03 appears to work well for detecting hydrogen, but its response time is too slow for critical applications. The sensitivity and speed of hydrogen detection can be enhanced by using the sensor film in a SPR configuration. However, in such a configuration the rapid desorption of water vapor can lead to a false indication of hydrogen whenever the sensor is exposed to a dry...

Fiber optic chemical and biological sensors, based on SPR in continuous metallic films deposited on optical fibers, have been previously reported. " Sensors based on optical fibers have advantages like high response times, ability to be remotely interrogated, and low electromagnetic interference. In our study, fiber optic devices were developed based on excitation of LSPs in gold nanoparticles, deposited on the surface and tip of different optical fiber stractures. As refractive index of the medium around the sensors was varied, or biological molecules attached to the nanoparticles, a shift in the plasmon resonance related dip in the transmission spectram was observed.

Over the last 15 years, numerous SPR sensors based on optical fibers or integrated optical waveguides have been proposed. Waveguide-based SPR sensors use either wavelength or intensity modulation and offer compact and miniature sensing elements with the ability to perform localized measurements in hard-to-access locations.

The avidin-biotin interaction has also been used to immobilize antibodies and proteins, especially in commercial systems based on surface plasmon resonance (SPR) measurements (e.g., the BIAcore). The extraordinary affinity (Kl 10-15 M) of avidin (or its bacterial relative, streptavidin) for the vitamin biotin is the basis of this immobilization procedure. A solid support (e.g., glass beads, sensor chip, optical fiber) covered with avidin can be used as an activated carrier for a very sturdy immobilization of previously biotinylated antibodies. In spite of the many methods for biotinylating proteins described in the literature, the use of biotinyl N-hydroxysuccinimide ester (BNHS) and similar derivatives, remains the most useful [65].

The optical flber SPR is the smaller device of this technology, allowing the use of this technique in distant locations. Sensors based on monomode and multimode optical flbers have been reported [23,24]. The cladding of the flber is partially removed and a gold layer is deposited symmetrically around the exposed fiber core. This type of fabrication limits the interaction area to a...
