GENERATION OF PULSATING PRESSURE WAVES, E.G. FOR CELL LYSIS

摘要

The present invention relates to a method by which a controlled source of heat (preferably a laser 3) generates a pulsating vapour bubble 4 in an enclosed liquid. The pulsating rate (the frequency) is preferably in the ultrasonic region, whereby cavitation occurs in the liquid. The cavitation effect will cause disruption of suspended components such as cells or bacterial spores. The ultrasonic disruption of cellular components is known as lysing by sonication.
