ABSTRACT:
The invention relates to a method for generating a convective liquid motion in a fluidic microsystem. According to this method, a liquid in a microsystem is simultaneously exposed to an electrical field and a thermal gradient. The electrical field is generated by means of an electrode arrangement which is subjected to a time-variant voltage. In this way, a time variant electrical field is formed in the liquid volume. The thermal gradient is produced by means of at least one radiation absorber located in the compartment which is exposed to at least one external radiation field.
