This video explains and illustrates how the discovery of sound measurement lead to a series of discoveries culminating in the knowledge needed to use sound in particle focusing.

The Attune® Acoustic Focusing Flow Cytometer, pictured to the left is the first cytometer that uses ultrasonic waves (over 2 MHz, similar to those used in medical imaging), rather than hydrodynamic forces, to position cells into a single, focused line along the central axis of a capillary.
