Determination of parabens in human urine by liquid chromatography coupled with electrospray ionization tandem mass spectrometry [PDF]
, 2014 A simple and sensitive method was developed for the simultaneous determination of methyl, ethyl,n-propyl,n-butyl, and benzyl parabens in human urine by liquid chromatography coupled with electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS).

Advanced Functional Materials, EarlyView.Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

Proton Dynamics in Protein Mass Spectrometry [PDF]
, 2017 Native electrospray ionization/ion mobility-mass spectrometry (ESI/IM-MS) allows an accurate determination of low-resolution structural features of proteins. Yet, the presence of proton dynamics, observed already by us for DNA in the gas phase, and its impact on protein structural determinants, have not been investigated so far.

Mass-Resolved Electronic Circular Dichroism Ion Spectroscopy [PDF]
, 2020 DNA and proteins are chiral: their three-dimensional structure cannot be superimposed with its mirror image. Circular dichroism spectroscopy is widely used to characterize chiral compounds, but data interpretation is difficult in the case of mixtures. We recorded for the first time the electronic circular dichroism spectra of DNA helices separated in a

Advanced Functional Materials, EarlyView.Zinc(II) coordination complexes with tunable aryloxy‐imine ligands exhibit controllable supramolecular self‐assembly into hierarchical fibrous structures. Coordination‐driven stacking, not π–π interactions, enables gelation, dynamic assembly/disassembly, and enhanced nanomechanical properties.

Structural study of analogues of Titan s haze by trapped ion mobility coupled with a Fourier transform ion cyclotron mass spectrometer [PDF]
, 2019 The aerosols present in the atmosphere of the Saturn s moon Titan are of particular planetary science interest and several spacecraft missions already allowed to gather spectroscopic data. Titan haze s analogs, so-called tholins, were produced on earth to push forward the comprehension of their formation and properties.
