    Acoustically driven mixing of small fluid volumes is reported. Using surface acoustic waves on a mixer chip and employing wave guiding effects in a substrate enables us to distribute a set of “virtual sources” for acoustic streaming over large areas. We demonstrate the applicability of our mixing technique to microarray applications, for mixing of individual wells in a micro titer plate, and other state-of-the-art hybridization assays.
