MEMBRANE AND METHOD FOR MICROMIXING

摘要

The present invention relates to a membrane and method for microfluidic mixing, the membrane having an upper membrane surface and a lower membrane surface and comprising at least one discontinuity. A composite may be formed by combination of two or more of the membranes. In a preferred embodiment the membrane generates a vortical acoustic streaming field when subjected to acoustic excitations. In one embodiment the method of mixing has efficiency of >80%, preferably >90% in 3 ms at a fluid flow rate of 60 μI/min.
