Nanobubbles in Electrospray Ionization Mass Spectrometry. [PDF]
Anal ChemNanobubbles (NBs) are very small gas-filled cavities in solvents, and when their sizes reach diameters around 200 nm, they remain in solution for extended periods of time, featuring special chemical and physical properties. Here, we investigate the application of NBs in electrospray ionization.
