Electrospray Post-Ionization Mass Spectrometry of Electrosurgical Aerosols [PDF]
The feasibility of electrospray (ES) ionization of aerosols generated by electrosurgical disintegration methods was investigated. Although electrosurgery itself was demonstrated to produce gaseous ions, post-ionization methods were implemented to enhance the ion yield, especially in those cases when the ion current produced by the applied ...

Electrospray ionization mass spectrometry with wooden tips: A review
Electrospray ionization (ESI) is a powerful ionization technique in mass spectrometry (MS). There has been an increasing interest for the new development of ESI technique to extend its applications. ESI-MS with wooden tips (wooden-tip ESI-MS), an ESI technique invented in 2011, enabled not only new applications but also new insights into the ESI ...

Electrospray ionization mass spectrometry of biotin binding to streptavidin [PDF]
Stepwise binding of biotin to streptavidin via several intermediates was monitored with electrospray ionization mass spectrometry (ESIMS). Protein ligand interactions that result in conformational changes could be recognized with ESIMS by a mass shift and a change of the average multiple charge state of this protein.

Electrospray ionization tandem mass spectrometry of monoketone curcuminoids [PDF]
RationaleAlthough monoketone curcuminoids (MKCs) have been largely investigated due to their biological activities, data on the gas‐phase fragmentation reactions of protonated MKCs under collision‐induced dissociation (CID) conditions are still scarce.

Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation
