FUNDAMENTAL PROPERTIES OF Nano Bubbles
Generally, water bubbles can be categorized into three major types, i.e., ordinary or macrobubbles, microbubbles (MBs), and nanobubbles (NBs). The diameter of macro-bubbles ranges from 100 μm to 2 mm. These bubbles quickly rise to the surface of a liquid and collapse. While microbubbles are smaller than macro-bubbles, with a diameter range of 1 μm–100 μm (Azevedo et al. 2019), these bubbles shrink in the water and then dissolve into it.
In contrast, NBs are extremely small gas bubbles that have several unique physical properties that make them very different from normal bubbles. Generally, NBs range <1 μm in diameter (Azevedo et al. 2019); however, the NBs that are <100 nm in diameter randomly drift in what is termed Brownian Motion and with a lower buoyancy can remain suspended in liquids for an extended period of time and have the ability to change the typical characteristics of water.
