A low-cost versatile fluorescence quenching detection system for liquid- and vapor-phase sensing
We report on the design and evaluation of a low-cost versatile optical sensor system to detect explosive traces by fluorescence quenching. In comparison to common detection systems, it allows to rapidly sample sensor arrays in various analyte carriers. Moreover, our work enables system development t...

Summary: | We report on the design and evaluation of a low-cost versatile optical sensor system to detect explosive traces by fluorescence quenching. In comparison to common detection systems, it allows to rapidly sample sensor arrays in various analyte carriers. Moreover, our work enables system development towards low-cost analysis and sensor testing solutions due to the simplicity of the approach. Therefore, we demonstrate the detection of nitroaromatic analytes in toluene, in water and in air by the application of transducing polymers. The results of the system demonstration indicate that the transduction strongly depends on the transducer state and on the analyte carrier. |
