Nanobubbles are nanoscopic and generally too small to be observed using the naked eye or a standard microscope, but can be observed using backscattering of light using tools such as green laser pointers. [12] Stable nanobubbles in bulk about 30-400 nanometers in diameter were first reported in the British scientific journal Nature in 1982. [12]
Hydroxyl radicals will form by the shrinking of microbubbles; it is due to an increase in the value of electromotive force on the liquid interface. Hydroxyl radical(•OH) and H + accumulate rapidly at the bubble interface. Ozone reacts with hydroxyl ions and hydroxyl radicals will form. The formation of hydroxyl radicals is pH-dependent.

When exposed to ultrasound, microbubbles oscillate in response to the incoming pressure waves in one of two ways. With lower pressures, higher frequencies, and larger microbubble diameter, microbubbles oscillate, or cavitate, stably. [5]
