    摘要: The invention relates to a microfluidic device for metering liquids into a microfluidic network. The microfluidic channels or chambers are at least partly formed by the introduction of suitable structures into a film above the substrate carrier, so that at least some of the flow of fluid through the network takes place above the plane of the substrate. In order to form a stable channel structure or chamber structure in the film, it is envisaged that in the edge zone between the unattached and attached portions a wedge of material is formed by the viscous flow of the film material as the film is bonded to the substrate, this wedge forming a transition between the chamber wall and the substrate and raising the chamber wall above the plane of the substrate. In one method of producing a finished microfluidic structure a flat planar film is laminated onto a flat sheet-like substrate. During the lamination a mask having at least one recess or opening is pressed onto the film and onto the substrate under pressure and/or under the effect of heat. The film is thereby brought to a temperature at which there is a viscous flow of film and/or substrate medium into the region of the recess or opening, so that a wedge of material is formed and the film bulges up in the region of the recess to form a chamber. The invention further relates to methods of metering at least one liquid in a microfluidic network, in which a capillary stop is overcome by actuating the film, the film being wetted as the capillary stop is removed.

    摘要: The invention relates to a method for measuring the scattered light (L2) of particles (P, PK) in a measuring medium (F), wherein a measuring container (1) is supplied with the measuring medium (F) and incident light (L1) is shone through the measuring medium (F) at least in some regions over a certain path length (1) and in a certain direction and the light (L2) scattered from the incident light (L1) is measured within a certain angle range (α).It is provided according to the invention that the incident light (L1) is guided parallel to a longitudinal axis (S) of the measuring container (1).By these measures, known methods can be improved and it is readily possible to use the invention even for very small measuring volumes of the measuring medium (F) with the associated small dimensions of the measuring container (1).

    摘要: A method and a device for the optical examination of a surface region are proposed. Fluorescence measurement is used to determine the amount of a substance bound to the surface region. Light interference is shut out thanks to the surface region being covered with an optically active liquid which filters, reflects, scatters and/or absorbs light with a wavelength at least substantially corresponding to the light radiated in and/or out.
