MICROFLUIDIC TESTING SYSTEM

摘要

The invention relates to a testing system comprising a fluid container (10) and an optical system (30) for the investigation of fluid samples. The fluid container (10) is provided with microchannels (13, 14) that contain and guide sample fluid. Active elements (1), particularly consisting of a hydrogel mixed with a light absorbing dye, are disposed in said microchannels. The active elements can be transferred from a non-activated state to an activated state with a different shape by a laser beam (35). This can be used to design micro valves and/or pumps. The laser beam (35) is preferably generated by an optical system (30) that is derived from the reading/writing unit of a Compact Disc player.
