    摘要: A device is disclosed for filtering a particle to be detected from a fluid. In at least one embodiment, the device includes a substrate and, applied above it, a protective layer, a channel being disposed between them for the purpose of receiving a fluid containing different particles. In at least one embodiment, the channel extends at least partially in a spiral shape between its inlet and outlet and on its internal wall contains a coating for attracting a particle type to be filtered, which coating is applied at least on the radially outside subsection of the internal wall of the channel. Owing to the laminar longitudinal movement of the fluid inside the channel a radially outward directed centrifugal force acts on the particles, with the result that per time unit more particles come into contact with the radially outside subsection of the internal wall of the channel than the radially inside subsection of the internal wall of the channel. The filter effect is reinforced as a result.

    摘要: An apparatus is disclosed for acquiring, detecting, and, optionally, analyzing cells in a biological liquid, which apparatus has a microfluidic system. In at least one embodiment, the apparatus includes at least one microfluidic channel having a small cross-section which is completely or partially coated with cell-specific binding molecules and which has no flow obstacles dividing the fluid flow; at least one apparatus for generating a steady and alterable liquid flow through the microfluidic channel, and optionally at least one apparatus for analyzing the genetic information of the cell. In at least one embodiment, the method includes a sample of a biological liquid being conducted through an apparatus defined above at a defined velocity V1 so that cells possibly present in the sample are bound to the cell-specific binding molecules; the sample of the biological liquid and/or a suitable liquid being conducted one or more times through the apparatus at a (different) defined velocity V2 so that nonspecifically bound constituents of the sample are removed; the cells bound to the cell-specific binding molecules being appropriately detected; and optionally the cells bound in the channel being released and the genetic information of the cells being optionally analyzed, with the ratio of the velocities, V1:V2, being in the range from 1:5 to 1:10.

    摘要: A device to extract material of a material reservoir has at least one guide tube with internal space and with an inner wall surrounding the internal space; at least one sled that can implement a sled translation movement in the inner space along a longitudinal alignment of the guide tube; and at least one collection unit with collection surface to collect the material. The collection unit and the sled are coupled to one another such that the sled translation movement of the sled leads to a collection translation movement of the collection surface of the collection unit, and such that the collection surface can be inserted into the material reservoir and be withdrawn from the material reservoir. A rotation mechanism that is operated manually or automatically can be provided with which a wire, which acts as a collection device, can be displaced in vivo over a length of 1 mm to up to 2 cm within a venous cannula. The invention is used in medical technology, for example, to collect cells from a reservoir in the form of a bodily fluid.

    摘要: A nanostructure is provided on a substrate by forming at least one multi-electrode arrangement on the substrate, wherein said electrodes comprise respective electrode areas projected with respect to the opposite electrode ends which extend along a line in such a way that the adjacent ends produce a respectively frequency time-variable potential difference. A suspension of nano-object such as nanotubes, nanowires and/or carbon nanotubes is produced and then transferred to the substrate between the adjacent ends. The assembly of respective individual nano-objects is dielectrophoreticly deposited on the line between said adjacent ends, and the assembly of respective nano-objects is fused in the area of the ends in such a way that the nanostructure is formed.
