Multi‐Targeting Non‐Specific Genome Engineering in Bacteria

Advanced Science, Volume 13, Issue 25, 4 May 2026.
In this study, we provide the first case to use the multi‐targeting integrase (MTI) systems in bacteria and develop a host‐independent generalizable approach, MNGE (Multi‐targeting Non‐specific Genome Engineering), for multi‐copy and random integration of metabolic genes or pathways in both Gram‐positive and Gram‐negative bacteria, which will ...

Engagement of a Neighboring Lys Residue by a Salicylaldehyde‐Modified Glycomimetic Ligand Enables Potent and Selective Binding to DC‐SIGN Over L‐SIGN

ChemistryEurope, Volume 4, Issue 5, May 2026.
Mannose derivatives connected to the aminophilic salicylaldehyde tag show high binding affinity for C‐type lectin DC‐SIGN, favored by an imine bond with a protein's Lys residue in the ligand binding site. This reversible‐covalent binding interaction enables ligand selectivity for DC‐SIGN over the closely related L‐SIGN.

Magnetism for the Quantification of Sorption in Porous Materials From Liquid Media

Chemistry–Methods, Volume 6, Issue 5, May 2026.
This adsorption quantification technique uses external magnetic fields and a magnetic holder to measure mass changes during adsorption, making it universally applicable to any adsorbate. Unlike standard methods, it requires calibration only for the adsorbent rather than for every analyte.
