Abstract: A handheld air sampler device for enrichment of airborne substances and/or particles, in particular microorganisms, includes: an inlet configured for air intake into a flow channel; an outlet configured for fluidic ally connecting the flow channel to an external vacuum device; a permeable backing element arranged in the flow channel, the backing element being configured to receive and support a filter element; and a sealing element configured for sealing a filter element received on the backing element such that, when a negative pressure is applied to the outlet, air entering the inlet forms an airstream passing the filter element and airborne substances and/or particles, in particular microorganisms, are enriched in the filter element. An air sampling arrangement includes a handheld air sampler device of this type.

Abstract: The invention discloses a method for detecting at least one antigen, comprising the following steps: providing magnetic beads, which are coated with antibodies specific for at least one antigen to be detected; bringing the magnetic beads in contact with a washing buffer that comprises at least 8% BSA and incubating the mixture with a sample; isolating the magnetic beads by means of magnetic separator; and detecting the antigens bound to the magnetic beads by the antibodies. Washing buffers, primers, kits and devices that can be used for said methods are also disclosed.

Abstract: The invention relates to a self-cleaning self-regenerating surface structure and/or a self-cleaning self-regenerating coating. For improving the cleaning function, the invention proposes a self-regenerating surface structure, especially coating, comprising biocatalytic and/or anti-icing molecules on an exposed surface of said surface structure, especially coating, and biocatalytic and/or anti-icing molecules embedded or contained in said surface structure, especially coating. Further, the invention relates to an object provided with such surface structure or coating and a method for producing the same.

Abstract: A device for the regeneration of a biosensor having an immobilized and biologically active material applied to the surface of a carrier that is suitable for interacting with a substance to be analyzed. The device comprises at least one injector through which, by means of a pump, at least one solution can be applied to the surface of the carrier for the purposes of rinsing the biologically active material.

Abstract: A device for the detection of micro particles that can be marked by probes or antibodies capable of being detected by radiation has a filter, a supply system, and a detection system. Fluid to be examined is passed over a filter to filter out the micro particles and to perform the marking steps by supplying corresponding marking substances to the filter.

Abstract: An apparatus and a method for automatic detection of particles, in particular, biological particles such as micro-organisms. The apparatus has a device for binding the particles to separating particles which can be bound selectively to the particles. The apparatus further includes a separating device for extraction of the separating particles with bound particles from a collecting fluid, and a detection unit for detecting a number and/or concentration of the particles separated in this manner. The device for binding the particles to the separating particles includes a collecting device for collecting a collecting fluid including the separating particles and the particles that are provided by a particle-fluid mixture.
