Ultrasonic Particle Concentration by a Line Driven Cylindrical Tube

Abstract
The invention is a means of acoustic manipulations of small particles in flowing streams.  It has been reduced to practice as an alternative to hydrodynamic focusing in flow cytometers, but the invention has applications in particle separation, microfluidic devices (see 2004-021), dialysis, blood/plasma separations, and chemical production.  The invention is a continuation of the acoustic sensing/manipulation inventions that have come from Dipen Sinha’s MST-11 laboratory.

Application(s)

• Flow cytometry
• Microfluids
• Separations

Advantages

• Reduced waste stream
