Surface acoustic wave (SAW) directed droplet flow in microfluidics for PDMS devices

Lab Chip. 2009 Sep 21;9(18):2625-7. doi: 10.1039/b906819h. Epub 2009 Jun 26.


We direct the motion of droplets in microfluidic channels using a surface acoustic wave device. This method allows individual drops to be directed along separate microchannel paths at high volume flow rates, which is useful for droplet sorting.
