Abstract
It has been shown that cavitation bubbles play essential roles in syntheses of nanoparticles by laser
ablation in liquids. The growth of nanoparticles inside the cavitation bubble was observed by a laser
light scattering experiment. The structure of synthesized nanoparticles was affected by the dynamics of
the cavitation bubble, indicating that nanoparticles were exposed in the high-pressure, high-temperature
reaction field of the collapsed cavitation bubble. In addition, an experiment carried out rather recently
suggests that the cavitation bubble stores significant amount of electrical charges.
