Robust Amorphous MOF‐Based Aerogels Digital Biosensor for Sensitive Detection of Organophosphate Pesticides

open access: yesAdvanced Science, Volume 13, Issue 48, 28 August 2026.
We report a robust aerogel digital biosensor by integrating an enzyme‐mediated amorphous MOF within an aerogel matrix for on‐site pesticide detection. The enzyme‐mediated assembly strategy enables in situ tailoring of MOF into a porous amorphous structure, achieving both high stability and activity.

Identification of chemicals targeting dementia genes and pathways in the Comparative Toxicogenomics Database

open access: yesAlzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Dementia is a public health challenge and exposures likely contribute to risk, though many have not been evaluated. We screened chemicals for enrichment with dementia genes and related pathways. METHODS We obtained gene lists from Agora and the Comparative Toxicogenomics Database (CTD) for 1008 chemicals and nine dementia‐related ...

Advanced Sorbent Materials in Solid‐Phase Extraction: A Decade of Innovation and Future Perspectives

open access: yesChemistry–Methods, Volume 6, Issue 8, August 2026.
This review systematically summarizes five families of advanced sorbent materials for solid‐phase extraction (SPE): nanocarbons, porous frameworks (MOFs/COFs), smart polymers, biomass‐derived sorbents, and multifunctional composites. Key molecular interactions (π–π stacking, hydrogen bonding, electrostatic attraction, host–guest recognition) are ...
