METHODS AND DEVICES FOR LIQUID-TREATING SUSPENDED PARTICLES

摘要

The invention relates to methods for treating at least one particle (10 - 13) with at least one reaction liquid (20) in a main channel (30) of a fluidic microsystem (100), comprising the following steps: moving the at least one particle (10 - 13) with a carrier liquid (40), which flows in a longitudinal direction of the main channel (30), up to a retaining device (50); at least partially retaining the at least one particle (13) under the action of a retention force exerted by the retaining device (50), and; feeding the reaction liquid (20) from at least one side channel (31) into the main channel (30) so that the at least one retained particle (13) is flown around by the reaction liquid (20). The retaining device (50) is placed in the main channel (30) downstream from a mouth (32) of the side channel (31), and the reaction liquid (20) flows through the retaining device (50) with a direction of flow that is oriented in the longitudinal direction of the main channel (30). The invention also relates to fluidic microsystems and electrode assemblies for carrying out said methods.
