Cold-spray ionization mass spectrometry: applications in structural coordination chemistry.
Electrospray ionization (ESI)-mass spectrometry (MS) is generally used for the characterization of labile supramolecules in which non-covalent bonding interactions are predominant. However, molecular ions are not detected in many cases because of their instability, and even if such ions are detected, thermal decomposition generates fragment ions that also appear in the mass spectrum. Cold-spray...
متن کاملElectrostatic-spray ionization mass spectrometry.
An electrostatic-spray ionization (ESTASI) method has been used for mass spectrometry (MS) analysis of samples deposited in or on an insulating substrate. The ionization is induced by a capacitive coupling between an electrode and the sample. In practice, a metallic electrode is placed close to but not in direct contact with the sample. Upon application of a high voltage pulse to the electrode,...
متن کاملElectrostatic spray ionization mass spectrometry imaging.
Imaging samples on a surface by mass spectrometry (MS) requires the combination of MS detection with a scanning mode that enables localized desorption and ionization and/or detection of sample analytes with good spatial resolution. We have developed a new mass spectrometry imaging (MSI) method based on electrostatic spray ionization. It works under ambient conditions and can be applied to a wid...
متن کاملFormation and destruction of the guanine quartet in solution observed by cold-spray ionization mass spectrometry.
The dynamic solution behavior during formation of the 2'-deoxyguanosine tetrad (G-quartet) upon addition of alkali metal cations and destruction of the G-quartet upon addition of the guanine-guanine mismatch recognition molecule naphthyridine dimer was observed by cold-spray ionization mass spectrometry.
متن کاملDirect Observation of Biomolecular Complexes by Cold-Spray Ionization Time-of-Flight Mass Spectrometry
Many biological processes are regulated by the specific and noncovalent intermolecular recognition between enzyme–substrate, antigen–antibody, receptor–ligand, carbohydrate–protein, and carbohydrate–carbohydrate. The direct observation of these biomolecular interactions is important for understanding the mechanisms behind these biological processes. Electrospray ionization mass spectrometry (ES...
