Abstract: The invention relates to a migration device (100) having a sample chamber (102), a migration matrix (105) arranged in the sample chamber (102), and a fluid outlet (103). The migration device (100) also has a discharge structure (104), which is designed to discharge fluids from the sample chamber (102) to the fluid outlet (103). The invention also relates to methods for operating the migration device and to the use of a migration device for determining the migration ability of ameboidally mobile cells.

Abstract: A method for at least partially applying a hydrophilic polymer to a measurement channel of a sensor cartridge is provided, which sensor cartridge can be replaceably inserted in an analyzer. The measurement channel comprises at least one sensor element. The method comprises inserting the sensor cartridge into the analyzer, introducing an aqueous solution containing chitosan or a chitosan derivative into the measurement channel of the sensor cartridge, and following a residence time replacing the aqueous chitosan solution with a gaseous or liquid medium, wherein residues of the chitosan or chitosan derivatives remain on the inside surface of the measurement channel and hydrophilize the surface.
