    摘要: The invention relates to a chemical sensor comprising a sensor film formed of a nanoparticle network in which the nanoparticles are interlinked by functionalized dendrimer molecules. The dendrimers support an efficient uptake of analyte molecules by the film material and therefore enable a high sensitivity of the sensor. In addition, the chemical nature of the dendrimers strongly determines the chemical selectivity of the sensor device. By cross-linking the components of the sensitive material the sensor displays a good mechanical stability.

    摘要: The application relates to a chemical sensor device comprising a substrate (1), a sensor medium (3) formed on the substrate, the sensor medium comprising one-dimensional nanoparticles, wherein the one-dimensional nanoparticles essentially consist of a semiconducting AxBy compound, e.g. V2O5 and detection means (2) for detecting a change of a physical property of the sensor medium e.g. conductivity. The porosity of the sensor medium supports a fast access of the analyte to the sensing material and therefore a fast response of the sensor. The selectivity and sensitivity of the sensor can be tailored by doping the one-dimensional nanoscale material with different dopants or by varying the dopant concentration. Sensitivity of the sensor device to an analyte, preferably an amine, can be increased by increasing relative humidity of the sample to at least 5%.
