本文综述了比色和荧光传感器阵列的发展和现状。基于化学响应着色剂（染料和纳米多孔颜料）的光学阵列探测分析物的化学反应性，而不是它们的物理性质。这为化学传感提供了高维度，允许高灵敏度（通常低至ppb水平），在非常相似的分析物之间进行令人印象深刻的区分，并在气相和液相中对各种分析物类型的极其相似的混合物进行精细的指纹识别。
A comprehensive review is presented on the development and state of the art of colorimetric and fluorometric sensor arrays. Optical arrays based on chemoresponsive colorants (dyes and nanoporous pigments) probe the chemical reactivity of analytes, rather than their physical properties. This provides a high dimensionality to chemical sensing that permits high sensitivity (often down to ppb levels), impressive discrimination among very similar analytes and exquisite fingerprinting of extremely similar mixtures over a wide range of analyte types, both in the gas and liquid phases.
