Abstract: A sensor kit for detecting an analyte. The sensor kit includes x indicator substances having a specific spectral response to the analyte, whereby 1?x?200. The sensor kit includes a substrate, which is to be illuminated on a first side and includes at least one indicator substance region arranged adjacent to a second side. Each indicator substance region is arranged for carrying one indicator substance and the substrate includes at least one indicator substance region for each indicator substance. A filter element is integrated with the substrate. The filter element includes at least one of each of n different filters, whereby 2?n?100. The filter element is arranged such that light firstly passes there through and thereafter through the indicator substance region(s). At least one of each of at least two different filters provides at least one indicator substance region with light when the substrate is illuminated.

Abstract: Novel peptide having a sequence according to SEQ. ID. No. 1, SEQ. ID. No. 2 and/or SEQ. ID. No. 3 are disclosed and also polypeptide scaffold consisting of a four helix bundle formed of two dimerized helix-loop-helix motifs, said helix-loop-helix motifs having sequences according to SEQ. ID. No. 1, SEQ. ID. No. 2 and/or SEQ. ID. No. 3 which may comprise a fluorescent probe at the side chain of Lys15 and a ligand with affinity for a target molecule at the side chain of Lys8 or Lys34. Also disclosed are polypeptide scaffolds for use in biosensing applications with or without the polypeptide scaffold anchored to a solid surface.

Abstract: This invention relates to a practical low cost method and devices which exploits the benefits of several photo-assisted analytical techniques involving controlled light sources. The method comprise the use of a program controlled display (like computer, mobile telephones to TV screens) used as a light source for illuminating a detector specially suited to capture the light interaction with a test environment, allowing to generate distinctive spectra and chemical or biochemical images of the environment. Additionally, the information can be acquired in situ but immediately analyzed on line via internet.

Abstract: In order to obtain long time stability and usefulness for gas sensitive field-effect devices a micro structured surface is obtained below the final conducting layer. The conductive layer in the trenches or grooves will not only be protected to some extent but also they can constitute a conductive net with edges or boundaries that will remain essentially unchanged even if material is continuously lost along the borderline. The structure can be obtained in the layer laying directly below the conductive layer or in deeper lying layers with intermediate layers with even thickness.

Abstract: Electronic odor detecting device (electronic nose) provided with a number of sensors. The gas that is to be subjected to the detection is brought to pass a number of similar or different sensors distributed on a surface. Between the sensors or actually extending between and past the sensors is a catalyst. The catalyst may be arranged on an opposing wall in a detection cell or in the same surface as the sensors. Constituents of the gas that react with the catalyst result in a different signal pattern for the sensors, depending on their location in relation to the catalyst. Since different substances in the gas will react with different rates in the presence of the catalyst, the sensed pattern will change along the catalytic surface. This makes it possible to evaluate a gas mixture with great precision and with a more limited number of sensors in comparison to prior art.
