A fiber optic sensor for nerve agent

Advances on Optical Fiber Sensors

“…Distributed optical fiber sensors based on evanescent field interactions enable the measurement of chemical distributions over very long distances. Their potential applications are in structural health monitoring, environmental monitoring, homeland security, and many other applications [93][94][95][96][97][98][99][100].…”

Fluorometric detection of a chemical warfare agent mimic (DCP) using a simple hydroxybenzothiazole–diaminomaleonitrile based chemodosimeter

“…8 To date, a variety of traditional analytical methods and devices have been developed to detect nerve agent mimics. These include mass spectrometry, 9,10 electrical sensors, [11][12][13] enzymebased biosensors, 14 enzymatic assays, 15,16 photoacoustics, 17 ion mobility spectroscopy, 18 lanthanide luminescence, [19][20][21] photonic crystals, 22,23 optical-fiber arrays, 24 and nanomaterials (nanotubes or nanowires). 25,26 However, these analytical methods require expensive instruments or complicated pre-treatment and suffer from low specificity, inadequate selectivity, reduced sensitivity, non-portability, and difficulties in real-time monitoring.…”

5.2.5 Polymer Optical Fibers as Gas Sensors

“…For gas sensing, different optical systems based on the evanescent wave absorption along optical fibers have been reported [1][2][3][4]. In such a system, a dye -which responds to the presence of a target molecule -is incorporated in a polymer or sol-gel matrix.…”
