acoustic cell sorting

Nano Mosh Pit

A biomaterials lab led by Gabriel Lopez has devised a way to grow uniformly sized particles of silicon gel  that can be sorted by soundwaves.  In a liquid chamber with a standing acoustic wave, most particles will gather at the nodes where the wave is standing still. But the new particles are actually attracted to the antinodes where the highest point of the wave is constantly shifting up and down. Attaching these new patent-pending particles to cells, proteins or other biological structures might allow them to be sorted at a fraction of the cost and effort of biological sorting systems now in use.
