Onosma armenum Extract Loaded Mesoporous Silica Nanoparticles for the Prevention of Biofilm‐Associated Infections

open access: yesChemistryOpen, Volume 15, Issue 4, April 2026.
Bioactive mesoporous silica nanoparticles (MSNPs) loaded with O. armenum extract were developed to evaluate their antibiofilm activity against biofilm‐forming Staphylococcus aureus ATCC 25923. The phytochemical content of the extract was analyzed via liquid chromatography–electrospray ionization tandem mass spectrometry.

Sequence‐Modulated Active Tripeptide Condensates for Tandem Catalysis

open access: yesAngewandte Chemie, Volume 138, Issue 13, 23 March 2026.
Sequence‐modulated tripeptide coacervates mimic biomolecular condensates with controllable, enzyme‐regulated phase separation. They co‐sequester hydrophobic active species and hydrophilic enzymes, enabling tandem catalysis in aqueous media. Incorporated into artificial cells, they function as adaptive sub‐organelles, orchestrating compartmentalized ...

Surface Functionalization of Polyetheretherketone With Immobilized γ‐Polyglutamic Acid for Enhanced Apatite Formation

open access: yesChemistryOpen, Volume 15, Issue 4, April 2026.
The authors developed chemical solution process to immobilize γ‐polyglutamic acid (γ‐PGA) onto polyetheretherketone (PEEK). Prior hydrophilic treatment using UV irradiation improved the immobilization efficiency of γ‐PGA and the apatite‐forming ability in simulated body fluid compared with acetic acid treatment.

Auxin‐Induced Nicotine Inhibition Is Mediated by NaARF5 Through the Suppression of NaERF1‐Like Expression and Interaction With NaERF1‐Like in Nicotiana attenuata

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 2642-2656, April 2026.
ABSTRACT Nicotine is the most abundant alkaloid produced by Nicotiana species against insect herbivores. Although it has been known for decades that auxin can strongly inhibit nicotine biosynthesis, the underlying mechanisms have remained unclear.
