本文综述了作者实验室近年来发展起来的利用光纤作为平台制作气敏阵列的方法。两种类型的基于荧光的光纤阵列系统的描述：聚合物涂层的单芯光纤和成像光纤束纳入功能化微球。每个系统以交叉反应的方式响应分析物蒸汽，生成多维信号，该多维信号可用于训练模式识别程序以识别阵列对学习蒸汽的后续暴露。描述了几种应用，包括爆炸物和神经毒剂检测以及几种挥发性有机化合物和易燃液体的检测。(C)2009爱思唯尔有限公司版权所有。
This paper reviews the use of optical fibers as a platform to fabricate vapor sensitive arrays that have been developed in the authors' laboratory in recent years. Two types of fluorescence-based optical-fiber array systems are described: polymer-coated single core optical fibers and imaging fiber-optic bundles incorporating functionalized microspheres. Each system responds to an analyte vapor in a cross-reactive manner generating a multi-dimensional signal that can be used to train a pattern recognition program to identify subsequent exposures of the array to learned vapors. Several applications are described including explosives and nerve agent detection as well as the detection of several volatile organic compounds and ignitable liquids. (C) 2009 Elsevier B.V.
