We have investigated the particle size distribution of nanobubbles (NBs) the nanoparticle tracking analysis method and found that the particle size is discrete and increases by a factor of √2. We interpreted that this peculiar particle size distribution is caused by the fact that NBs of the same size tend to coalesce with each other, and simulated the particle size distribution incorporating this effect, and found that it can generally reproduce the experiment. The results of recent studies on the interfacial structure of NBs will also be presented.
