Title : Nanobubbles and Applications
Abstract:
Microbubble and nanobubble technologies have gotten a lot of interest in recent years because of their vast range of applications in science and technology, including water treatment, biomedical engineering, and nanomaterials. There are also several intriguing physicochemical aspects that are currently unsolved, and numerous groups are still working on them.
Within liquids, nanobubbles (NBs) are gas-filled nano-sized particles. Surface nanobubbles (SNBs) and bulk nanobubbles (BNBs) are named after their locations in the solid/liquid interface and in the solution, respectively. Apart from that, micropancakes are shaped like spots with a width of several microns but a height of only 1-2 nm.
In the first part of the study, the difference, structure, production methods and characterization methods of surface and bulk nanobubbles will be mentioned. In 1950, where Epstein-Plesset proposed a theory to predict the lifetime of a single bubble as a function of the bubble radius and saturation. However, this theorem cannot explain the longevity of nanobubbles. For this reason, various theorems have been put forward. In our study, the stability of nanobubbles will be emphasized and the theorems related to their stability will be explained.
Their interesting physical properties and potential biomedical applications have led to a rapid increase in research in this area, demonstrated by search results of the term 'Nanobubble' into the Web of Science online database. Current studies range from previously described use as theranostic agents, pharmaceutical agents, fundamental studies on stability and behavior to nonpharmaceutical applications such as cleaning and agriculture. In the last part of the study, different and various application ways of nanobubbles will be explained with examples.
