<p>A method is provided for displacing small amounts of fluids in micro channels, in which an amount of fluid is introduced into a channel system which has at least one area which corresponds in a topological manner to a ring, such that a closed path of the fluid is possible, and acoustic waves, which have at least one asymmetrical component on the plane of the channel system, are radiated into the fluid, this component defining the direction of displacement of the fluid. A micro channel system for carrying out the method is also provided.</p> |
