Oxygen release from nanobubbles adsorbed on hydrophobic particles

On the hydrophobic particles, the carrying capacity of nano/microbubbles and the quantity of oxygen released in the hypoxic environment are still unknown while the bubbles blow out. This is very important to the biological and medical systems. Here, an experiment was designed and the change of the dissolved oxygen in a solution was monitored. The results indicated that the concentrations of dissolved oxygen in hypoxic environment changed dramatically, especially when the ultrasound vibration was applied. Furthermore, the amount of oxygen release also implied the quantity dependence of nano/microbubbles on the sizes and the hydrophobicity of the particles.
