摘要： The invention relates to a gas detection system (1) for detecting gases, vapors and biological pathogens, having at least one receptor (4) arranged on a line (5) connecting the ambient air (7) to an air storage unit, wherein the gas detection system (1) is designed as a “breathing” system containing clean CO
2 -carrying and moisture-saturated air in the air storage unit (2), wherein the operating temperature of the gas detection system (1) is the room temperature. Additionally, a method is proposed for detecting gases, vapors and biological pathogens using the inventive gas detection system. This avoids the shortcomings of the known solutions of the prior art, and an improved and more cost-effective solution for detecting trace gases is made available.-

摘要： The invention relates to a detector for detecting highly toxic gaseous or vaporized hazardous substances or warfare agents. In order to be able to detect such substances quickly and easily at ambient temperature, a substrate comprising a hydrogen (H)-terminated or hydrogenated surface is used as a warfare agent detector. The substrate is equipped with a measuring instrument for measuring shifts of surface charges on the hydrogen (H)-terminated or hydrogenated surface. The substrate is made of a semiconductor material or a non-conductive material that has surface conductivity.

摘要： The present invention relates to a gas sensor (1) for detecting gases, with at least one gas-sensitive layer which is applied to a substrate (2), wherein at least one conductor track (3) for contact-connecting the layer is also provided on the substrate (2), and wherein the conductor track (3) is formed from a doped metal oxide material with non-catalytic properties in order to avoid the conductor track (3) influencing the detection of the gas. This avoids the disadvantages of the prior art and provides contact-connection of the gas-sensitive layers which does not influence the sensitive properties when detecting the gas by means of the layer.

摘要： The invention relates to a device and a method for detecting microparticles that can be labeled by probes, which can be detected by radiation, or antibodies. In order to allow a fast, straightforward and automated detection, the fluid to be assayed for microparticles is guided across a filter (24) in order to filter out the microparticles (32) and the labeling steps are carried out by guiding corresponding labeling substances towards the filter (24). The invention especially allows an automatic detection of living bacteria by means of in situ hybridization.

摘要： A micromechanical filter for microparticles is suitable in particular for filtering pathogenic bacteria and viruses, and comprises a substrate and a perforated membrane permanently connected to the substrate, for filtering out microparticles from a medium while flowing through the membrane, and furthermore a device for removing the filtered-out microparticles from the surface of the membrane. The device for removing the microparticles is embodied, for example, as a heating device, in order to burn the microparticles located on the surface of the membrane. It can also be embodied as an actuator structure for deforming the membrane or as a microinjector for generating a flow parallel to the surface of the membrane.

摘要： The invention relates to a semiconductor gas sensor (10) comprising a gas-sensitive layer (5), a heater (3) for heating the layer to a defined measurement temperature and contact electrodes (6a, 6b) for measuring the electric resistance of the gas-sensitive layer (5), and a micro-chamber (7) in which the gas-sensitive layer (5) is positioned. The micro-chamber (7) can be closed off towards the exterior and is configured such that its volume is so small that at least one component of the gas or gas mixture to be analyzed is at least to a large extent depleted within a defined measurement period by reaction on the gas-sensitive layer. Owing to the limited gas supply and the reaction of one component of the gas during the measurement gases or gas mixtures containing several components can be analyzed, the measurement signal being obtained after at least one component has reacted. Several sensor elements with gas-sensitive layers can be arranged in the chamber, which can be operated at different temperatures. A gas-sensor system consists, for example, of at least two semiconductor gas sensors with micro-chambers (7) which are arranged in a system comprising gas lines and valves and can be individually filled.
