Molecules that only differ by their chirality, so called enantiomers, often possess different properties with respect to their biological function. Therefore, the separation of enantiomers presents a prominent challenge in molecular biology and belongs to the ``Holy Grail'' of organic chemistry. This talk we will start with a short overview over the theoretical background and some of the experimental applications of surface acoustic wave generated flows in microfluidic systems. In this context we suggest a new separation technique for chiral molecules that is based on their transport properties in a microfluidic flows with spatially variable vorticity. Because of their size the thermal, fluctuating motion of the molecules must be taken into account. These fluctuations will be shown to play a decisive role in the proposed separation mechanism.
