• Antimicrobial peptide mechanism of action on S. aureus membranes determined by in vivo solid-state NMR · 2026

  Résumé de la publication : Staphylococcus aureus (S. aureus) is a Gram-positive pathogenic bacterium and a major cause of nosocomial infections. Between 20 % and 50 % of S. aureus strains are resistant to a wide range of antibiotics. DMS-DA6-NH 2 (DA6) is a novel antimicrobial peptide…

• Ultra‐Fast Isothermal Formation of DNA Nanostructures in Culture Media: Application to In Situ Assembly of DNA Origami With Living Cells · 2026

  Résumé de la publication : Synthetic DNA strands are programmable and biocompatible building blocks that can be combined through hybridization to form user‐defined nanostructures, but their assembly traditionally requires cell‐incompatible conditions, imposing a lengthy ex situ fabrication step before any application with living matter. Here we demonstrate…

• Wall Teichoic Acids Are Direct Molecular Targets of Antimicrobial Peptides in Gram-Positive Bacteria · 2026

  Résumé de la publication : Lytic antimicrobial peptides (AMPs) are long recognized for their ability to disrupt bacterial membranes, yet their interactions with other cell-envelope components remain poorly understood. Such knowledge is essential for redesigning AMPs as next-generation antibiotics or tailoring them for strain-specific activity. Here we…

• Induced Photoelectron Circular Dichroism as a Probe for Distinguishing Diastereotopic Lone Electron Pairs · 2026

  Résumé de la publication : The hydrogen-bonded complexes of phenol with the chiral molecule methyloxirane (MOx) have been studied under supersonic jet conditions by photoelectron circular dichroism (PECD) experiments based on a resonance-enhanced two-photon ionization scheme. Ionization of the achiral phenol moiety within the complex leads to…

• Tracing the Origin of Driving Force of Photoinduced Interfacial Electron Transfer Reaction by Colocated Scanning Electrochemical Microscopy · 2026

  Résumé de la publication : Solar energy is the ultimate power source for mass and energy conversions on this planet through photochemical reactions. Among these, photoinduced interfacial electron transfer (PIET) reactions are driven by photofield-induced Volta potentials, fundamentally different from classical electrochemical processes by directly applied potential…
