Abstract: 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%.

Abstract: 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.

Abstract: The invention relates to a nanoparticle film comprising a nanoparticle network formed of nanoparticles interlinked by linker molecules. The linker molecules have at least two linker units that can bind to the surface of the nanoparticles. By introducing selectivity-enhancing units in the linker molecule, the selectivity of the nanoparticle film towards target analytes can be enhanced. A fine-tuning of the selectivity can be achieved by including a fine-tuning unit in the vicinity of the selectivity-enhancing unit. The nanoparticle film can be used to produce chemical sensors which are selective and stable in their performance.

Abstract: An optical/electrical conversion element used for a photosensor or a solar battery. An optical/electrical conversion layer, composed of an assembly of a light-absorbing dendrimer structure (1), operating as an electron donor, and fine metal particles (2), operating as an electron receptor, are self-collectively formed by imparting chemical affinity to the dendrimer structure and to the fine metal particles. With the present optical/electrical conversion element, in which the light-absorbing substance has a dendrimer structure, the electrons, excited on light absorption, migrate over a long distance via molecular chain to get to the fine metal particles (2) operating as an electron receptor. The electrons are routed quickly to outside as current via contact among the fine metal particles and/or between the fine metal particles and an electrode.
