Nanobubbles (NBs) are nanoscopic gaseous domains than can exist on solid surfaces or in bulk liquids. They have attracted substantial attention due to their long-time (meta)stability and a high potential for real-world applications. Using an approach not previously investigated, we exploit surface-electrostatic NB formation and stabilization via application of external electric fields in gas-liquid systems, with the marked result of massively increased gas uptake into the liquid in NB form. The de facto gas solubility enhancement (over many months) ranges from 2.5-fold for oxygen to 30-fold for methane vis-à-vis respective Henry’s law values for gas solubility; the more hydrophobic the gas, the more spectacular the increase. Molecular dynamics simulations reveal that the origin of NBs’ movement lies in dielectrophoresis, while substantial NB stabilization arises from a surface-polarization interaction.

纳米气泡（NB）是纳米级的气态域，其存在于固体表面或散装液体中。由于它们的长期（亚）稳定性和在实际应用中的巨大潜力，它们引起了广泛的关注。使用以前未研究的方法，我们通过在气液系统中施加外部电场来利用表面静电NB的形成和稳定化，其显着结果是大量吸收了NB形式的气体。相对于气体溶解度的相应亨利定律，事实上的气体溶解度提高（数月之久）从氧气的2.5倍到甲烷的30倍不等。气体疏水性越强，增加的幅度就越大。分子动力学模拟表明，NBs运动的起源在于介电泳，
