在纯水中通过等离子体形成直径小于400 nm的纳米气泡。预击穿等离子体称为流光放电，产生的气体通道形状像细树枝状珊瑚，导致形成小气泡。通过光学显微镜观察纳米气泡，并通过动态激光散射测量。然而，有必要验证这些纳米气泡是气泡，而不是固体，因为还观察到了污染物，如来自电极的铂颗粒和有机化合物以及超纯水中的残留物。
Nanobubbles of less than 400 nm in diameter were formed by plasma in pure water. Pre-breakdown plasma termed streamer discharges, generated gas channels shaped like fine dendritic coral leading to the formation of small bubbles. Nanobubbles were visualized by an optical microscope and measured by dynamic laser scattering. However, it is necessary to verify that these nanobubbles are gas bubbles, not solid, because contamination such as platinum particles and organic compounds from electrode and residue in ultrapure water were also observed.
