The present invention relates to a method for detecting an analyte, which is based on the detection of a signal caused by a change of the mechanical properties of a permeable freestanding nanoparticle composite. The present invention also relates to a method for determining the concentration of and/or recognizing an analyte.

The present invention relates to a method of altering the sensitivity and/or selectivity of a chemiresistor sensor, to a sensor and a sensor array produced by such method.

Method of altering the sensitivity and/or selectivity of a chemiresistor sensor

The application relates to a chemical sensor device comprising a substrate (), a sensor medium () formed on the substrate, the sensor medium comprising one-dimensional nanoparticles, wherein the one-dimensional nanoparticles essentially consist of a semiconducting ABcompound, e.g. VOand detection means () 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%.

The present invention relates to a method of forming a film of nanoparticles interlinked with each other using a polyfunctional linker.

Method of forming a film of nanoparticles interlinked with each other using a polyfunctional linker

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.

Chemical sensors from nanoparticle/dendrimer composite materials

The present invention relates to a chemical sensor arrangement having an analyte sensitive indicator wherein the analyte sensitive indicator has at least one nanoparticle. The invention further relates to a method for providing nanoparticles of defined and different sizes, especially for a chemical sensor arrangement, wherein a nanoparticle solution, having nanoparticles of a broad size distribution, is applied to chromatography beads, whereby the nanoparticles are adsorbed onto said beads and classified by size, and beads of a specific layer, having nanoparticles of essentially the same size, are separated from the beads within other layers and are held in suspension.

Chemical sensor arrangement

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.

Electrochemical apparatus and process for purification of fluids

Disclosed is an electronic device comprising a nanoparticle structure and configured such that, when driven by a power source, a current path is defined through said nanoparticle structure, wherein the nanoparticle structure comprises a substrate and metal and/or semiconductor nanoparticles, wherein the nanoparticles are linked to each other and/or to the substrate by bifunctional or polyfunctional ligands. The invention especially relates to an electronic device in the form of a sensor for detecting one or more analytes in a liquid or a gas phase.
