The role of surface in desorption electrospray ionization-mass spectrometry: advances and future trends

, 2020
An outlook on the current status and trends in desorption electrospray ionization-mass spectrometry (DESI-MS), one of the most common spray-based techniques for ambient ionization, is given with a focus on the main advances recently achieved or still in

Towards greener yttrium‐catalyzed ring‐opening polymerization via an all‐terpene reaction concept

Polymer International, EarlyView.
Development of a terpene‐based catalytic system for ring‐opening polymerization of bio‐based lactones that reveals the steric effects of the nucleophile on initiation and alkoxide exchange, while simultaneously enabling post‐polymerization functionalization.

Combining Laser‐Induced Edition to Collision‐Induced Sequencing of Digital Oligomers in a Single Gas‐Phase Experiment

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale To increase the confidentiality level of molecular tags, binary information can be hidden in sequence‐defined oligomers using isobaric monomers including a photo‐sensitive one, which mass can be modified upon light irradiation. Reading such secured data requires light edition prior to MS/MS sequencing, which was investigated here in ...

Hydrogen Is the Superior Nebulization Gas for Desorption and Electrospray Ionization

Analytical Chemistry
A previous comparative study between helium and nitrogen as nebulizing and desolvation gases in electrospray ionization (ESI) and desorption electrospray ionization (DESI) found that the signal responses of compounds of varying sizes and polarities were improved. Here, an expanded selection of nebulizing gases was evaluated to investigate mechanisms of

Cross‐Linking Mass Spectrometry of the Antimicrobial Peptides Magainin 2 and PGLa Reveals Heterodimerization in Micellar Medium

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale In this study, we applied cross‐linking mass spectrometry (XL‐MS) to characterize the oligomeric states of a PGLa/magainin 2 mixture and gain insight into the heterodimerization previously suggested in the literature. Both peptides have shown a synergistic enhancement of activity when tested in antimicrobial assays; however, the ...

Ambient desorption ionization mass spectrometry (DART, DESI) and its bioanalytical applications

, 2020
In recent years, ambient desorption ionization techniques for mass spectrometry were introduced. Among them, the most established techniques are Direct Analysis in Real Time (DART) and Desorption Electrospray Ionization (DESI).

Use of analytical strategies to understand spatial chemical variation in bacterial surface communities

Journal of Bacteriology
Not only do surface-growing microbes such as biofilms display specific traits compared to planktonic cells, but also they display many heterogeneous behaviors over many spatial and temporal contexts.

Exploring the Fragmentation of Sodiated Species Involving Covalent‐Bond Cleavages for Metabolite Characterization

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Electrospray (ESI), the most popular desorption/ionization technique used in mass spectrometry‐based metabolomics, generates both protonated and deprotonated molecules, as well as adduct ions, sodium being the most frequent monoatomic cation entering their composition.

Solid-Phase Extraction Strategies to Surmount Body Fluid Sample Complexity in High-Throughput Mass Spectrometry-Based Proteomics

Journal of Analytical Methods in Chemistry, 2015
For large-scale and standardized applications in mass spectrometry- (MS-) based proteomics automation of each step is essential. Here we present high-throughput sample preparation solutions for balancing the speed of current MS-acquisitions and the time ...
