阵列传感器采用人工模拟嗅觉系统的传感模式,实现多点信息的同时获取,极大地提高了分析效率,在公共安全、环境监测、医学检测等领域具有广阔的应用前景。其中,光化学阵列传感器因灵敏度高、输出信号丰富等优点而备受关注。近年来,为了进一步提高阵列传感器的识别能力和灵敏度,功能化纳米材料被广泛应用于光化学阵列传感器以增加传感材料的种类和发展新的传感方法。本文按照使用的光谱检测技术不同,详细介绍了功能化纳米材料在荧光、比色、催化发光和多通道阵列传感器等4类光化学阵列传感器中的应用。
The array sensor adopts the sensing mode of artificial simulated olfactory system to realize the simultaneous acquisition of multi-point information, which greatly improves the analysis efficiency and has broad application prospects in the fields of public safety, environmental monitoring and medical detection. Among them, the photochemical array sensor due to high sensitivity, the output signal rich and other advantages and much attention. In recent years, in order to further improve the recognition capability and sensitivity of array sensors, functionalized nanomaterials are widely used in photochemical array sensors to increase the types of sensing materials and to develop new sensing methods. In this paper, the application of the functionalized nanomaterials in four types of photochemical array sensors such as fluorescence, colorimetric, catalytic luminescence and multi-channel array sensors is introduced in detail according to the different spectral detection techniques used.
