What is NanoGAS®?


What is NanoGAS®?

By generating bubbles of less than 1μm (micrometer) nanosize in a liquid and changing the gas trapped inside, NanoGAS® has been confirmed to be highly effective in maintaining the freshness of food, fermentation, promoting the growth activity of animals and plants, and special cleaning. These invisible bubbles are widely applied in various fields such as medicine, fermentation and brewing, special cleaning, iron and steel, cultivation and aquaculture, and beauty care.

What is NanoGAS®?

The cloudy white bubbles often seen in bubble baths are called microbubbles or millibubbles, but in the case of NanoGAS®️, which has bubbles even smaller than those, the liquid is colorless and transparent to the eye.

Millibubbles, such as champagne bubbles, are highly buoyant and escape rapidly into the atmosphere in a short period of time, but nano-sized NanoGAS®️ has almost no buoyancy and does not escape into the atmosphere.

In order for bubbles to dissolve more efficiently in liquids, it is necessary to maintain a state of equilibrium where “buoyancy” and “gravity” are in balance, which is achieved by NanoGAS®.

NanoGAS®, developed by Symbiosis Corporation, is the world’s first technology that makes it possible to keep bubbles in liquids dissolved for as long as 10 years.

It has various characteristics that differ greatly from microbubbles and millibubbles, and is attracting attention as a next-generation technology.


Special characteristics1Invisibly small bubbles

One thousandth of a meter is one millimeter (mm), one millionth of a meter is one micrometer (μm), and one billionth of a meter is one nanometer (nm). In other words, 1 nm (nanometer) is one billionth of 1 m (meter), which is larger than the difference between the diameter of the earth and that of a one yen coin.

Incidentally, bacteria are several micrometers in size and viruses are tens to hundreds of nm in size.

The gas dissolution and inclusion functions made possible by the ultra-fine bubbles of “NanoGAS®” are expanding the range of applications in a variety of fields, including pharmaceuticals.

Benefits to be gained
  • NanoGAS® is liquid and portable: no need to set up production facilities
  • Cost reduction and productivity improvement through unprecedented cleaning power

Special characteristics2A film of bubbles is a film of charges.

A unique feature of NanoGAS®️ is that the membrane covering the bubbles is a film of electric charges.

It is not a film of oil like a soap bubble, but is bordered by a liquid by the action of electrons.

In other words, NanoGAS®️ water is manufactured using only natural ingredients.

In addition, it can be utilized without additives or chemicals such as surfactants because it penetrates into the microscopic gaps between substances.

Benefits to be gained
  • Promotes growth activity of plants and animals
  • Maintains freshness of foodstuffs and controls bacteria
  • Increase in body temperature and improvement of blood flow in the human body
  • Oxygen supply to oxygen-deprived cells
  • Hydrogen supply to oxidized cells

Special characteristics3 Physical adsorption/cleaning action (exfoliation action)

Since NanoGAS®️ in water is negatively (minus) charged, bubbles repel each other and do not combine. Since the bubbles do not grow large, they can exist in the liquid for a long period of time.

The negative charge of the bubbles also allows them to lift up and peel off even the smallest dirt, since organic dirt is mainly positively charged. The bubble’s own crushing energy and the cross-linking action (surfactant action) it exerts when it encounters a substance enable efficient cleaning.

The redox potential of the liquid can be controlled by changing the density and size of the bubbles and the gases to be enclosed, as they have the property of lowering the redox potential of the liquid.

Benefits to be gained
  • Prevention of food oxidation
  • Activation of life activities in plants and animals
  • Removal of oxidative stress, which is said to be the cause of all diseases
  • Efficient cleaning of dirt
  • High affinity with fats and oils

Our patented NanoGAS® technology uses bubbles that do not disappear even after 10 years.

Bubble technology is expected to be used not only for cleaning, sterilization, and deodorization, but also in various industries such as steel, fisheries, and agriculture. While many companies are considering the potential of the technology itself, there have been reasons why the industry as a whole has not progressed in its application.

One of the reasons for this is the technical challenges involved (in long-term stability of the bubble).

Can be manufactured using only water and gas

Until now, the technical challenge of nanobubbles’ practical application has been the inability to stabilize bubbles in liquids and their disappearance. We have developed a technology that can stabilize bubbles in liquids for a long period of time by fundamentally reviewing existing nanobubble production technology.

The general nanobubble generator uses a technique called rotary shearing. We have patented equipment and manufacturing methods for both the rotating mixer and the bubble shear filter for the shearing portion of this process.

The combination of these patented technologies enables us to offer unrivaled quality.

Patented technology for long-term stabilization of bubbles

We are in the process of applying for and obtaining patents for NanoGAS® technology in Japan and overseas.

NanoGAS® size and number measurement verification

Unfortunately, there is still no instrument in the world that can accurately measure bubbles of a few nm in size. We measured the number and density of particles using Beckman Coulter's Coulter counter method, which is currently the world standard for particle measurement

  • Equipment used: Beckman Coulter
  • Multisizer 4e Minimum detection limit: 200 nm
  • Dilution value: 4000x
  • Product type: Hydrogen NanoGAS® water

Although the number of bubbles has decreased after 10 years, a comparison of only bubbles with a lower detection limit of 200 nm or larger showed the presence of approximately 34% more fine bubbles of the same size. Compared to general bubble products, which are said to have a lifespan of several hours to several months, our NanoGAS® technology, which uses highly functional nanobubbles, has outstanding performance in terms of long-term stability. Change over time in NanoGAS®water particle counts

"I've honestly never seen numbers like these."

We received these words from the person in charge of the manufacturer, the world standard for particle measurement. We are not satisfied with our current technology and will continue to develop it. *The graph appears to be cut off in the middle because the minimum detection limit is 200 nm, but it is assumed that there are a large number of even smaller bubbles.

NanoGAS® Size and Number Measurement Verification Commentary from Tomohiro Yoneda, Beckman Coulter K.K.

For companies considering the use of NanoGAS®.

The high-performance nanobubble technology behind NanoGAS® is expected to be used in a great many fields as an environmentally friendly and safe “next-generation material” because it is multifunctional and requires only water and air as materials

Improved solubility of gases and solutes and the ability to contain a variety of gases

One of the properties of ultrafine bubbles is “self-pressurization”.
This is the action of an increase in the pressure inside a gas that allows the gas to efficiently dissolve into the liquid beyond its saturation level.
By changing the gas enclosed in the foam, it is possible to add additional functions to NanoGAS®️ water and maximize the properties of the gas.
Self-pressurization also acts to increase the saturated concentration of various substances (solutes) dissolved in the liquid (solvent) that holds the foam.
