Our acoustic sorter combines the advantages of traditional fluorescence-activated cell (FACS) and droplet sorting (FADS) and is applicable for a multitude of objects. We sort aqueous droplets{,} at rates as high as several kHz{,} into two or even more outlet channels. We can also sort cells directly from the medium without prior encapsulation into drops; we demonstrate this by sorting fluorescently labeled mouse melanoma cells in a single phase fluid. Our acoustic microfluidic FACS is compatible with standard cell sorting cytometers{,} yet{,} at the same time{,} enables a rich variety of more sophisticated applications. }, doi = {10.1039/C4LC00588K}, url = {http://dx.doi.org/10.1039/C4LC00588K}, author = {Schmid, Lothar and Weitz, David A and Franke, Thomas} }
