    摘要: 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.
