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.
