What are nanobubbles?

Imagine a grain of salt. It is really small. Now, divide it into 2500 smaller grains. This is the size of a single gas nanobubble.

Nanobubbles behave differently than gas bubbles we know from our everyday life. They have also changed the way scientists think of properties of gases dispersed in liquids.

Thanks to their extraordinarily small size, high surface pressure and negative charge they stay in water for weeks, changing its properties for a long time.

All gases existing in the natural environment can take the form of nanobubbles.

The use of nanobubbles in various industries is a very efficient and energy-saving strategy. Thanks to nanobubbles, a much higher gas concentration in a liquid can be achieved, thus providing much better and long-lasting results.

Due to their small size, nanobubbles are able to penetrate spaces that larger particles cannot get into. In addition, due to their negative charge, they attract other substances. These may be impurities, which explains why water with nanobubbles cleans surfaces without the need of detergent usage. Nanobubbles also attract various active substances and become their medium, which is used e.g. in medicine.

Nanobubbles have also a wide range of applications in agriculture and food industry, as they enhance crop performance, allow to limit the quantity of chemicals used and effectively clean food products.
