What are Nanobubbles

Nanobubbles are extremely small gas bubbles—typically less than 200 nanometers in diameter—suspended in a liquid like water. Despite their tiny size, nanobubbles behave very differently from larger bubbles and have unique physical, chemical, and interfacial properties that make them valuable in many industries.

A nanobubble is a spherical gas cavity in a liquid medium with a diameter typically ranging from 20-nm to 200-nm, possessing high internal pressure, negative surface charge (zeta potential), and unusually long stability, even though classical theory would suggest they should dissolve almost instantly.

1. Size: < 200 nanometers (1,000× smaller than a grain of sand).
2. Stability: Can remain stable in liquid for days, weeks, or even months.
3. Buoyancy: Essentially neutrally buoyant (they don't rise like normal bubbles).
4. Surface Charge: Typically carry a negative zeta potential, reventing coalescence.
5. High Internal Pressure: Due to surface tension, pressure inside can be several atmospheres.
6. Large Surface Area: Extremely high surface area-to-volume ratio.
7. Disappearance: They shrink and dissolve (do not burst like large bubbles).

Nanobubbles interact physically and chemically with their surroundings in several ways:

• Dissolution: They gradually release gas (like O₂, H₂, CO₂) into the liquid, improving oxygenation or altering pH.
• Collapse Effects: If triggered to collapse (e.g., via ultrasound), they generate localized heat, pressure, and free radicals (oxidizing agents).
• Surface Interaction: Their negative charge and nanoscale size help them adhere to surfaces, disrupt biofilms, and loosen contaminants.
