Synthesizing silicone gel particles

Full Text:

Pictured at left are silicone gel particles. Duke University engineers have devised a way to grow silicone gel particles that can be sorted in a way unlike any others of their kind. In a liquid chamber with a standing acoustic wave, most particles gather at the nodes where the wave is standing still. These new particles, however, are attracted to the antinodes where the highest point of the wave is constantly shifting up and down. By tagging these new patent-pending particles onto cells, proteins or other biological structures, they can be sorted at a fraction of the size, cost, time and effort compared to current widely used methods.
