The present invention involves an artificial nose having an array comprising at least a first dye and a second dye in combination and having a distinct spectral response to an analyte. In one embodiment, the first and second dyes are from the group comprising chemoresponsive dyes, and the second dye is distinct from the first dye. In one embodiment, the first dye is selected from the group consisting of porphyrin, chlorin, chlorophyll, phthalocyanine, and salen, or their metal complexes. In another embodiment, the second dye is selected from the group of dyes consisting of acid-base indicator dyes and solvatochromic dyes. The present invention is particularly useful in detecting metal ligating vapors. Further, the array of the present invention can be connected to a visual display device.
本发明涉及一种人工鼻,其具有包括至少第一染料和第二染料的阵列组合,并对分析物具有独特的光谱响应。在一种实施例中,第一和第二染料来自包括化学响应染料的组,第二染料与第一染料不同。在一种实施例中,第一染料从卟啉,叶绿素,叶绿素,酞菁和萨伦或其金属配合物组成的组中选择。在另一种实施例中,第二染料从酸碱指示剂染料和溶剂致变染料组成的染料组中选择。本发明在检测金属配位汽化物方面特别有用。此外,本发明的阵列可以连接到视觉显示装置。
