The importance of nanobubbles is widely acknowledged, particularly in terms of their role
with respect to bubble size and stability. Nanobubbles are tiny spherical cap-shaped
bubbles, and have several unique physical and mechanical characteristics. Longevity,
virtual disappearance of buoyancy, high internal pressure, extremely large surface/volume
ratio, high oxygen dissolution rate, and generation of free radicals are the important features
of nanobubbles. Their peculiar characteristics have led to many applications in the various …
