Nanobubbles in Electrospray Ionization Mass Spectrometry. [PDF]

open access: yesAnal Chem
Nanobubbles (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.

Analysis of Oligonucleotides by Electrospray Ionization Mass Spectrometry [PDF]

open access: greenCurrent Protocols in Nucleic Acid Chemistry, 2000
AbstractBecause of the high molecular weights and thermal lability of biomolecules such as nucleic acids and protein, they can be difficult to analyze by mass spectrometry. Such analyses require a “soft” ionization method that is capable of generating intact molecular ions.
