Nanobubbles (NB) have various unique properties. We investigated the size distribution of nanobubbles by nanoparticle tracking analysis, and revealed that the bubble size is discrete and that the bubble size increases by a factor of √2. This specific size distribution is interpreted as being due to the fact that nanobubbles having the size coalesce preferentially. We performed a simulation of the particle size distribution incorporating this effect, and found that it could reproduce the experimental results.
