Abstract: The invention relates to a method for determining the coagulation time of a sample fluid containing blood components by means of a resonator whose vibration parameters are measured and then used as a basis for determining the sample fluid viscosity change, which resonator has an at least partially adhesive surface contacting said sample fluid. The invention is characterized by preincubation of said surface with a preincubation fluid containing blood components, which preincubation fluid has a known way of interacting with the coagulation system, thus resulting in anchoring sites to be formed on the adhesive areas of said surface.

Abstract: The invention relates to a method and a device for producing a molded body having microstructures from molding material. The method for producing a molded body having microstructures on a carrier out of molding material is effected by inputting a molding material into a container (10) comprising a mold cavity (14), wherein at least one micro-structured mold (12) is provided in the mold cavity. Furthermore, the centrifugation of a container (10) is carried out until the molding material has completely entered into the structure of the mold (12). Thereafter, the curing of the molding material is carried out to form a molded body having microstructures, which is then removed from the mold (12) and the container (10).

Abstract: The invention relates to a method for determining haemostasis parameters by measuring vibration parameters of a resonator having a measuring surface which contacts a platelet containing sample fluid. The invention is characterized by the analysis of the characteristic of a vibration parameter over time, based on which the platelet function will then be assessed and a distinction will be made between the presence of an adhesion disorder or that of an aggregation disorder.
