No Dye Fits All: Illuminating the Challenges of Fluorescent Extracellular Vesicle Labeling

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
ABSTRACT The widespread use of fluorescent dyes for extracellular vesicle (EV) labeling has substantially improved our ability to trace EVs in vitro, ex vivo, and in vivo. However, interpretability of these experiments remains limited by methodological challenges, including incomplete dye removal, dye‐associated artifacts, and intrinsic EV ...

Host Factor Induced Bacterial Extracellular Vesicles Promote Horizontal Gene Transfer in Vibrio cholerae

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
Antimicrobial stressors, that is, bile or mitomycin C, induce enlarged, nucleic acid‐rich bacterial extracellular vesicles in Vibrio cholerae that facilitate horizontal gene transfer in vitro and during intestinal colonisation. The findings provide a detailed comparison of control versus stress‐induced vesicles, identify bile as a host factor shaping ...

Photoinduced Selective Construction of Densely Functionalized Spirocyclic Ethers With Carbyne Equivalents

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
A reactivity programmed cascade between carbyne equivalents and allylic benzoates was developed that sequentially orchestrates all three reactivity modes of carbyne equivalents, enabling the rapid installation of three σ‐bonds at a single carbon center and providing efficient, scalable access to structurally diverse spirocyclic ethers. ABSTRACT Carbyne

Substrate‐Tight Graphene Transmembrane‐nanofluidic Devices

Small, Volume 22, Issue 25, 4 May 2026.
This study demonstrates that the covalent coupling of a pyrene layer to a silicon nitride substrate using silane and peptide chemistry increases the adhesion of graphene to the substrate and prevents the delamination of graphene. 76.2% of the devices with free‐standing graphene are successful devices for ion transport measurement in 0.1 M HCl ...

High Spin Iron–Phosphinidene and Arsinidene Complexes With Attenuated Metal–Ligand Multiple Bond Character

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Unusually low metal–ligand bond orders are observed in high spin iron(II) pnictogenidene (PH2– and AsH2–) complexes. Electronic structure analysis provides evidence for multiconfigurational character that attenuates the metal–ligand multiple bond character normally that is typically associated with pnictogenidene ligands. These complexes can be used to
