DNA shearing

High powered ultrasound waves can produce gaseous cavitation (see figure 1) in liquids.

Cavitation is the formation of small bubbles of dissolved gases or vapors due to the alteration of pressure in liquids. These bubbles are capable of resonance vibration and produce vigorous eddying or microstreaming.

This mechanical stress has multiple effects on biological samples including; effective cell lysis, DNA and chromatin shearing as well as homogenization.
