Abstract

Remote sensing in environmental applications has been widely employed as an alternative to traditional sampling methods. Fluorometric techniques have be- come one of the most popular methods of detection because of high sensitivities and simplicity of equipment, and have allowed the measurement of numerous toxic organic and inorganic materials. Laser excitation linked with fiber optic transmission make even the most remote environment accessible. By placing fluorogenic reagents at the tip of the fiber optic system, non-fluorescent analytes may react with the indicator dyes to change the fluorescent properties in the sensing volume, and thi
