Abstract

The use of optical fibers as chemical sensors is becoming increasingly widespread and diverse, ranging from probes for determining enzyme activities to detecting contaminates in underground water. Of particular interest to this research group is the area of fiber optic fluorosensing. Typically, the probe is a bifurcated fiber bundle, where part of the bundle is used to transport the excitation radiation to the sample, and the remaining fibers deliver the emission to the detector. The common end of the bundle is placed in the sampling environment. Alternatively, a fiber fluorosensor can be simply a single fiber, serving both transportation and collection purposes.
