Hadamard Transform Ion Mobility Spectrometry Based on Matrix Encoding Modulation
Sensors, 2023 Ion mobility spectrometry (IMS) has been widely used for the on-site detection of trace chemicals, but continue to suffer from a low duty cycle of ion injection.

High-Pressure Ion Mobility Spectrometry [PDF]
Analytical Chemistry, 2009 The effects of above-ambient pressure on ion mobility on resolving power, resolution, and ion current were investigated using a small, stand-alone ion mobility spectrometer (IMS). This work demonstrates the first example of ion mobility spectrometry at pressures above ambient.

Investigation of Dendriplexes by Ion Mobility-Mass Spectrometry
Molecules, 2014 Highly branched polyamidoamine (PAMAM) dendrimers presenting biological activities have been envisaged as non-viral gene delivery vectors. They are known to associate with nucleic acid (DNA) in non-covalent complexes via electrostatic interactions ...

Chemical standards in ion mobility spectrometry [PDF]
The Analyst, 2010 In ion mobility spectrometry (IMS), reduced mobility values (K(0)) are used as a qualitative measure of gas phase ions, and are reported in the literature as absolute values. Unfortunately, these values do not always match with those collected in the field.

Right in two: capabilities of ion mobility spectrometry for untargeted metabolomics
Frontiers in Molecular Biosciences, 2023 This mini review focuses on the opportunities provided by current and emerging separation techniques for mass spectrometry metabolomics. The purpose of separation technologies in metabolomics is primarily to reduce complexity of the heterogeneous systems

Measurement of acetates in air using differential ion mobility spectrometer
E3S Web of Conferences, 2017 Volatile organic compounds are one of the most important group of air pollutants. Potential health and environmental problems resulting from their emission prompted the requirement for monitoring these species. It motivates development of new measurement

Biomolecule Analysis by Ion Mobility Spectrometry [PDF]
Annual Review of Analytical Chemistry, 2008 Although nonnative protein conformations, including intermediates along the folding pathway and kinetically trapped misfolded species that disfavor the native state, are rarely isolated in the solution phase, they are often stable in the gas phase, where macromolecular ions from electrospray ionization can exist in varying charge states. Differences in

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations
FEBS Letters, EarlyView.The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...
