Nanobubbles are 50-120 nm in diameter. The most peculiar characteristic of these bulk nanobubbles is their extraordinary longevity. Whilst the lifetime of microbubbles (1-1000 microns) is on the order of seconds, nanobubbles last for weeks and months. Nanobubbles are a breakthrough technology in gas-liquid systems that may perhaps revolutionise existing processes.
Exceptional physicochemical properties that distinguish them from conventional bubbles. These unique characteristics enable superior gas transfer, stability, and treatment efficiency.
Nanobubbles possess unique physical and chemical properties that make them effective across agriculture, water treatment, aquaculture, food processing, healthcare, mining, and many other industries.
The unique properties of nanobubbles enable improvements in oxygen transfer, biological activity, and water treatment, making them effective across a wide range of applications.
How Do We Measure Nanobubbles
Nanokriti characterizes nanobubbles using Nanoparticle Tracking Analysis (NTA), enabling accurate measurement of particle concentration, size distribution, and stability.
NTA (Nanoparticle Tracking Analysis) is a widely used technique for analyzing nanoparticles and nanobubbles in liquids. It works by using a laser to illuminate the particles and tracking their natural Brownian motion in real time. This allows accurate measurement of particle size, concentration, and distribution at the nanoscale. At NanoKriti, NTA is used to verify the presence and stability of nanobubbles, ensuring consistent quality and reliable performance across applications such as water treatment, agriculture, aquaculture, environmental research, and industrial processes.
Why is the laser beam clearly visible in one container but almost invisible in the other?
The difference is caused by nanobubbles. In DI water, the laser passes through with minimal light scattering, so the beam is barely visible. In nanobubble water, the suspended nanobubbles scatter the light, making the beam clearly visible through the Tyndall effect. This simple experiment offers an easy way to observe the presence of nanobubbles and understand how they interact with light.

Frequently Asked Questions
Find answers to some of the most common questions about nanobubbles, their properties, and how they work across different applications.
What are nanobubbles?
Nanobubbles are extremely small gas-filled bubbles, typically less than 1 micron in diameter. Their unique size and stability allow them to remain suspended in water much longer than conventional bubbles.
How are nanobubbles different from ordinary bubbles?
Unlike ordinary bubbles that quickly rise and burst, nanobubbles remain dispersed in water for extended periods, providing more efficient gas transfer and a larger surface area for interaction.
Which gases can be used to generate nanobubbles?
Nanobubbles can be generated using air, oxygen, ozone, nitrogen, carbon dioxide, and other gases, depending on the application and the desired treatment outcome.
How are nanobubbles measured and characterized?
Nanobubbles are characterized using techniques such as Nanoparticle Tracking Analysis (NTA), Dynamic Light Scattering (DLS), and Zeta Potential Analysis, along with water quality measurements.
Are nanobubbles visible to the naked eye?
No. Nanobubbles are far smaller than the wavelength of visible light, making them invisible individually, even though they remain dispersed throughout the water.
Why are nanobubbles used in so many applications?
Their ability to improve oxygen transfer, enhance oxidation, and support biological processes makes nanobubbles valuable across agriculture, aquaculture, water treatment, and many industrial applications.
