1. A method for producing a microfluidic system on a polymer surface wherein at least one portion of the polymer surface is irradiated by laser light in a targeted fashion for the spatially-resolved modification of the wettability of the portion of the polymer surface by a liquid sample, the method comprising irradiating at least one portion of the polymer surface with laser light having different parameters for each of the at least one portions, thereby generating a hydrophilic-hydrophobic pattern on the polymer surface, wherein at least a first one of the portions of the polymer surface is hydrophobized by the laser light, at least a second one of the portions of the polymer surface is hydrophilized by the irradiation with laser light, and the laser light comprises an intensity below an ablation threshold of the polymer.
