    What Are Nanobubbles?

    Nanobubbles are tiny, long-lasting, gas-containing cavities in aqueous solutions. Due to their unique physical and mechanical characteristics they can be used to optimize water resources, improve processing techniques, increase production, and offer scalable solutions in the various fields of science and technology, including industrial, biological, and medical fields.

    Unique Nanobubble Characteristics

    Bubble Size

    Nanobubbles are generally classified as being less than 200 nanometers (nm) in diameter. Unlike larger size bubbles that increase in size, rise rapidly and burst at the water surface, nanobubbles remain stable in water for an extended period of time due to their strong negative surface charge and neutral buoyancy.

    The SIO patented method consistently generates high-density solutions of optimally sized nanobubbles, averaging 85 nm in diameter, as confirmed by independent laboratory testing using Malvern’s NanoSight Nanoparticle Tracking Analysis software. These nanobubbles maintain stability in liquid by achieving equilibrium with surface tension, internal pressure, surrounding liquid pressure, surface charge, and their environment.

    In collaboration with Tokyo Metropolitan University’s Fluid Engineering Laboratory, research findings and experimental results directly inform our product manufacturing processes.

    Neutral Buoyancy

    Nanobubbles are neutrally buoyant and can remain suspended in liquid for months and due to the Brownian Motion will travel randomly throughout the body of water. This unique behavior enables nanobubbles to provide a homogeneous distribution of gas throughout the water column and efficiently aerate the entire body of water.

    Smaller Bubbles, Greater Reactivity

    The surface area between bubbles in water filled with nanobubbles is much greater than water filled with larger bubbles. This increase in the surface area allows for higher gas mass transfer rates and increases the efficiency of chemical reactions with any dissolved or suspended components in the water.

    One ml of 100 nm diameter nanobubbles has 1000 times more surface area than one ml of 0.1 mm diameter bubbles

    Surface Charge

    One of the important properties of nanobubbles is the electrical charges on the bubble surface which determines the interaction of nanobubbles and how they interact with other materials such as solid particles or oil droplets. The electrical potential of a particle in a colloidal system can be expressed by the Zeta-potential.

    High And Low Zeta Potential

    The zeta potential is measured in mV and it measures the magnitude of the attraction between particles and bubbles or electrostatic repulsion. It is a useful indicator for understanding the state of the nanoparticle surface charge and in predicting the long-term stability of dispersions.

    A high zeta potential signifies stability to nanobubbles in a suspension due to repulsion among the bubbles. Conversely, a lower zeta potential leads to coagulation and is less stable.

    Nanobubbles have a high negative surface charge that keeps them stable in liquid and enables them to continuously participate in and stimulate physical, biological, and chemical interactions.


    Gas Reserve

    SIO nanobubbles boast neutral buoyancy and a negative surface charge, enabling them to stay suspended for months, forming a reservoir of entrained oxygen. As water consumes oxygen, these nanobubbles swiftly diffuse additional oxygen into the water, maintaining elevated dissolved oxygen levels. This extra gas reserve, estimated to be up to 20% beyond the saturation point, ensures highly efficient and consistent gas transfer in various water treatment processes.


    an electrical double layer emerges as two parallel layers of opposing charges on an object’s surface when exposed to a fluid. Typically, a solid surface carries a negative charge, attracting a second layer of positive ions.

    In aqueous solutions, Nanobubbles carry a robust negative charge, drawn to the electrical double layer, replacing liquid-solid interfaces with gas-solid interfaces. This process enhances the effective slip length, diminishing frictional drag in liquids, and improving lubricity.
