Nonuniform Chiralization of Metal-Organic Frameworks Using Imine Chemistry

Berend Smit, Emad Oveisi, Natalia Gasilova, Sauradeep Majumdar, Elias Moubarak, Balázs Álmos Novotny, Kevin Maik Jablonka, Andres Adolfo Ortega Guerrero

Homochiral metal-organic frameworks (MOFs) are exceptional media for heterogeneous enantiodifferentiation processes. Modifying available achiral structure-bearing MOF scaffolds is a preferred method to extend this class of materials. Reported postsynthetic ...

Rapid Untargeted Puff-by-Puff Analysis of (Electronic) Cigarette Emissions by Concentric Dielectric Barrier Discharge Ionisation Mass Spectrometry

Natalia Gasilova, Laure Menin, Luc Patiny, Maria Pavlou

Despite the soaring popularity of e-cigarettes among teenagers and young adults, our understanding of the full extent of their health hazards have remained limited. This is due to the vast complexities of e-cigarette aerosols and the difficulty in their fu ...

Adding Color to Mass Spectra of Biopolymers: Charge Determination Analysis (CHARDA) Assigns Charge State to Every Ion Peak

Yury Tsybin, Natalia Gasilova, Laure Menin, Anton Kozhinov, Konstantin Nagornov

Traditionally, mass spectrometry (MS) output is the ion abundance plotted versus the ionic mass-to-charge ratio m/z. While employing only commercially available equipment, Charge Determination Analysis (CHARDA) adds a third dimension to MS, estimating for ...

Dielectric barrier discharge ionization procures characteristic adducts of polyfluoroalkyl substances (PFAS) amenable by gas chromatography-mass spectrometry

Natalia Gasilova, Laure Menin

Fluorotelomer alcohols (FTOHs) and acrylates (FTACs) have been reported as precursors of perfluoroalkyl acids and are known to contaminate biotic and abiotic compartments. Here, a detailed study was carried out for assessing the capability of dielectric ba ...

Site-selective template-directed synthesis of antibody Fc conjugates with concomitant ligand release

Natalia Gasilova, Jean-Manuel Segura, David Viertl

Template-directed methods are emerging as some of the most effective means to conjugate payloads at selective sites of monoclonal antibodies (mAbs). We have previously reported a method based on an engineered Fc-III reactive peptide to conjugate a radionuc ...

High-Throughput Sizing, Counting, and Elemental Analysis of Anisotropic Multimetallic Nanoparticles with Single-Particle Inductively Coupled Plasma Mass Spectrometry

Andreas Züttel, Natalia Gasilova, Cedric David Koolen, Wen Luo, Mo Li, Ayush Agarwal

Nanoparticles (NPs) have wide applications in physical and chemical processes, and their individual properties (e.g., shape, size, and composition) and ensemble properties (e.g., distribution and homogeneity) can significantly affect the performance. Howev ...

Tyrosine bioconjugation with hypervalent iodine

Jérôme Waser, Natalia Gasilova, Laure Menin, Nina Declas

Hypervalent iodine reagents have recently emerged as powerful tools for late-stage peptide and protein functionalization. Herein we report a tyrosine bioconjugation methodology for the introduction of hypervalent iodine onto biomolecules under physiologica ...

Characterization of the Time-Domain Isotopic Beat Patterns of Monoclonal Antibodies in Fourier Transform Mass Spectrometry

Natalia Gasilova, Laure Menin

The time-domain transients in the Fourier transform mass spectrometry (FTMS) analysis of monoclonal antibodies (mAbs) are known to exhibit characteristic isotopic beat patterns. These patterns are defined by the isotopic distributions of all gaseous mAb io ...
