The path of biomolecular mass spectrometry into open research

Nature Communications, 2019
Originally designed for measuring isotope abundances and elemental masses, mass spectrometry is becoming a mainstay across life sciences. As electrospray ionization of biomolecules turns 30 and the Orbitrap mass analyzer 20, we take this opportunity to ...

Investigating the Structure–Function Relationships of Fluorinated Interfaces for PFAS Capture and Electrochemically‐Mediated Release

Advanced Functional Materials, EarlyView.
This study explores the use of fluorinated copolymers with varying fluorophilic side chain lengths to enhance PFAS affinity. The integration of electrochemical techniques demonstrates enhanced adsorbent regeneration, with molecular dynamics simulations providing insight into the molecular‐level interactions involved.

Comparison of Two Detection Methods for Fragment Ions of Escherichia coli Carbon Center Metabolites

Journal of Pure and Applied Microbiology, 2018
Mass spectrometry is an analytical technique for molecules detection after separating the particle motion (charged molecules, atoms and fragment ions) according to their mass-to-charge ratio, under the action of an electric field and a magnetic field ...

Rapid method for Mycobacterium tuberculosis identification using electrospray ionization tandem mass spectrometry analysis of mycolic acids [PDF]

, 2013
Mycolic acids (MAs), which play a crucial role in the architecture of mycobacterial cell walls, were analyzed using electrospray ionization tandem mass spectrometry. A targeted analysis based on the 10 most abundant and characteristic multiple reaction

Copper Doping Enhances the Activity and Selectivity of Atomically Precise Ag44 Nanoclusters for Photocatalytic CO2 Reduction

Advanced Functional Materials, EarlyView.
By a simple anti‐Galvanic reaction, up to six copper atoms could be preferably doped into the Ag2(SR)5 staple motifs and Ag20 dodecahedral shell of an atomically precise Ag44(SR)30 nanocluster. When anatase TiO2 is used as substrate, the (AgCu)44/TiO2 photocatalyst exhibited much improved activity in photocatalytic CO2 reduction compared to Ag44/TiO2 ...

Studies on Transition Metal-Quercetin Complexes Using Electrospray Ionization Tandem Mass Spectrometry

Molecules, 2015
To systematically study the effects of the number of d electrons of the first transition metal ions (Fe, Co, Ni, Cu and Zn) on the formation and stability of metal flavonoid complexes, we took the quercetin/M2+ complex as a model system to investigate ...

Mass Spectrometry-based Methods for Phosphorylation Site Mapping of Hyperphosphorylated Proteins Applied to Net1, a Regulator of Exit from Mitosis in Yeast [PDF]

, 2002
Prior to anaphase in Saccharomyces cerevisiae, Cdc14 protein phosphatase is sequestered within the nucleolus and inhibited by Net1, a component of the RENT complex in budding yeast. During anaphase the RENT complex disassembles, allowing Cdc14 to migrate
