As BBB disruption with ultrasound and microbubble treatment has shown to be a safe and promising treatment pre-clinically, two clinical trials are testing delivery of doxorubicin [47] and carboplatin [48] with microbubbles to increase drug concentration locally.
A nanobubble is a small sub-micrometer gas-containing cavity, or bubble, in aqueous solutions with unique properties caused by high internal pressure, small size and surface charge.
Hydrodynamic cavitation is the process of vaporisation, bubble generation and bubble implosion which occurs in a flowing liquid as a result of a decrease and subsequent increase in local pressure. Cavitation will only occur if the local pressure declines to some point below the saturated vapor pressure of the liquid and subsequent recovery ...
Ozone micro/nano-bubble technology improves the disinfectant capacity of ozone. [ 2 ] Ozone is a strong oxidizing agent widely used in the treatment of printing and dyeing wastewater, [ 3 ] and coal chemical wastewater. [ 4 ]
The animal snaps a specialized claw shut to create a cavitation bubble that generates acoustic pressures of up to 80 kPa at a distance of 4 cm from the claw. As it extends out from the claw, the bubble reaches speeds of 60 miles per hour (97 km/h) and releases a sound reaching 218 decibels. The pressure is strong enough to kill small fish.

They are simply smaller test tubes inserted upside down in another test tube so they are freely movable. The culture media to be tested is then added to the larger tube and sterilized, which also eliminates the initial air gap produced when the tube is inserted upside down. The culture media typically contains a single substance to be tested ...
