First Claim
Patent Images
1. A method for acoustically manipulating a particle using radial acoustic focusing comprising:
- introducing into a channel a first fluid having a first acoustic contrast with a population of particles suspended therein;
introducing into the channel a second fluid having a second acoustic contrast that is greater than or equal to the acoustic contrast of the first fluid;
applying a radial acoustic radiation pressure to the channel; and
acoustically focusing at least a portion of the population of particles from the first fluid to the second fluid.
