Oxygen Nanobubble configuration and mechanism of 5mC hypermethylation. (a) Schematic representation of oxygen nanobubble; (b) Oxygen nanobubbles (red arrows) localize within HeLa cells in the cytoplasm as well as the nucleus. Significantly enhanced dark field microscopy images are provided. Scale bar = 10 µm.
