传感器阵列是基于对动物嗅觉系统的认识发展起来的一种有力的分子识别手段,其由一系列传感单元组成,通过各传感单元对样品响应后产生的特征图谱实现对特定物质的识别检测,尤其对混合样品的鉴定具有突出优势。其中,荧光传感器阵列由于具有灵敏度高、无需参照体系、输出信号丰富、能够成像等优点,已成为近年来传感器阵列发展的重点。本综述根据荧光传感单元形式的不同,分别介绍了溶液型、颗粒型、薄膜型荧光传感器阵列的发展情况,并重点阐述了荧光传感器阵列的设计方法、传感机理及其在对金属离子、有机化合物和生物分子识别中的应用。
Sensor array is based on the understanding of animal olfactory system developed a powerful molecular recognition means, which consists of a series of sensor units, through the sensing unit of the sample response characteristics of the resulting spectrum to achieve the detection of specific substances , Especially for the identification of mixed samples has outstanding advantages. Among them, the fluorescence sensor array has become the focus of sensor array development in recent years because of its advantages of high sensitivity, no need of reference system, rich output signal and imaging. In this review, the development of solution-type, particle-type and thin-film fluorescent sensor arrays are introduced respectively according to the different forms of fluorescent sensing elements. The design method, sensing mechanism and application of fluorescent sensor arrays are also discussed. Organic Compounds and Biomolecular Recognition.
