METHOD FOR MANUFACTURING A MICROFLUID SYSTEM ON A POLYMER SURFACE

摘要

The method for producing a microfluidic system on a polymer surface (17), comprises specifically irradiating a sub-area of the polymer surface by a laser light to modify the wettability of the sub-area by a liquid sample in spatially resolved manner. The polymer surface is structured and chemically changed through the irradiation with the laser light. A diameter of the polymer surface is less than 4 cm. A hydrophilic-hydrophobic-sample is produced on the polymer surface by irradiating with the laser light of different parameters in different sub-areas.

The polymer surface is structured and chemically changed through the irradiation with the laser light. A diameter of the polymer surface is less than 4 cm. A hydrophilic-hydrophobic-sample is produced on the polymer surface by irradiating with the laser light of different parameters in different sub-areas. A test element (13) is produced for determining analytes in a fluid and comprises a polymer carrier (18) with the polymer surface, a task zone (15) for the sample of the fluid, a detection zone (16) for determining the analytes and a capillary channel (14) for transporting the sample of the task zone into the detection zone. The capillary channel is provided in the polymer carrier. The polymer surface is hydrophilized inside the capillary channel through the irradiation with the laser light. The polymer surface is hydrophobized around the task zone through the irradiation. An independent claim is included for a microfluidic system.
