摘要:
Gassy and degassed aqueous solutions of DNA were treated ultrasonically while monitoring the field for discrete cavitation events. At irradiation intensities greater than about 500 W/cm2, transient cavitation is shown to be responsible for the observed reduction in molecular weight. At intensities of 200 to 288 W/cm2, degradation of DNA was observed which did not depend upon transient cavitation.
