Abstract

On the basis of elastic waves released by imploding cavitation bubbles, a mechanism for biological cell disintegration in high intensity ultrasound has been proposed. Comparison of this mechanism with the published results on yeast cells shows many points of agreement suggesting that yeast cell disintegration in ultrasonic cavitation occurs by shear stresses developed by viscous dissipative eddies arising from shock waves.

摘要

基于空化泡内爆释放的弹性波,提出了一种高强度超声作用下生物细胞解体的机制。将该机制与已发表的关于酵母细胞的研究结果进行比较,发现许多一致之处,这表明超声空化作用下酵母细胞的解体是由冲击波产生的粘性耗散涡所形成的剪应力导致的。
