Nanobubbles are tiny gas bubbles in liquids, typically smaller than 200 nanometers in diameter. They have unique properties, such as high stability and the ability to penetrate surfaces, making them useful in water treatment, medicine, and agriculture.
Bubble size comparison:
- Nanobubbles: < 200 nm (extremely small, stable, invisible to the naked eye)
- Microbubbles: 1–100 µm (larger, visible under a microscope, rise slowly)
- Millibubbles: > 1 mm (common bubbles, quickly rise and burst)
Nanobubbles stand out because they remain suspended in liquid longer and dissolve more efficiently compared to larger bubbles.
Applications of Nanobubbles:
Industry:
- Water purification: Nanobubbles can be used to remove contaminants from water, such as heavy metals, oils, and organic substances.
- Enhancing plant growth: Nanobubbles can increase oxygen availability for plant roots, leading to faster growth and higher yields.
- Fish farming: Nanobubbles improve water quality in aquaculture, increasing oxygen availability, which benefits fish health and growth rates.
- Increasing the efficiency of chemical processes: Nanobubbles can accelerate chemical reactions, improving efficiency and reducing energy consumption.
Medicine:
- Targeted therapy: Nanobubbles can be used to deliver drugs, genes, or other therapeutic substances directly to diseased cells, minimizing side effects on healthy tissues.
- Medical imaging diagnostics: Nanobubbles can be used as contrast agents in medical imaging techniques such as ultrasound, MRI, and CT scans, enhancing the visibility of anatomical structures and enabling early disease detection.
- Ultrasound therapy: Nanobubbles can be activated by ultrasound, causing them to collapse and release energy, which can be used to destroy cancer cells or break up blood clots.
Other applications:
- Cosmetics: Nanobubbles can be used to transport active ingredients deep into the skin, improving its condition and appearance.
- Energy: Nanobubbles can be utilized to enhance the efficiency of fuel cells or solar collectors
Why plants need more oxygen?
A dramatic increase in the level of oxygen provided to the plant root system makes it stronger, healthier and prone to assimilate nutrients more easily.
Oxygen plays a massive role in the metabolic processes and enables rapid and healthy plant growth resulting in crop yields higher up to 20%.
Nanobubbles of oxygen allow much better nutrient uptake by the root system, which consequently leads to a significant cut back on fertilizers used.
Improvement in water quality Oxygen has strong oxidative properties, thus cleansing water of unwanted chemicals, such as heavy metals while enhancing the growth of beneficial probiotic microorganisms.
