Deep-learning fluorescence array quantified multiple PFAS in water
A fluorescence sensor array combined with deep learning quantifies multiple PFAS contaminants in water samples simultaneously, providing rapid screening for environmental monitoring.
F6H8 altered human liver cell metabolism and produced a PFAS-like metabolite
—
in BiochemistryF6H8, an ophthalmic treatment for dry eye, produces PFAS-like metabolites and triggers broad metabolic disruption in human hepatocytes, raising long-term safety concerns.
PFOS detected rapidly with a dual-recognition chemiresistive sensor
Chemiresistive sensor with molecularly imprinted polymer and fluorine-fluorine interactions achieves 1.3 ng·L⁻¹ detection of PFOS in environmental samples with validated accuracy.
Home-produced eggs had the highest PFAS levels in Croatia
Study measuring per- and polyfluoroalkyl substances in Croatian eggs across production systems, identifying home-produced eggs as significantly more contaminated and young children as most vulnerable.
PFAS aerosols concentrated in fine particles under chamber conditions
Controlled chamber study of PFAS aerosol formation reveals size-dependent inhalation deposition patterns. Most PFAS show fine-mode aerosols with peaks at 0.3 micrometers, while bacterial seed.
Sunlight-driven photocatalyst cleaves PFAS carbon–fluorine bonds
Z-scheme photocatalyst CuInS2/BiOCl composite enables visible-light-driven degradation of PFAS through directed charge transfer, achieving 96% removal in sunlight-driven continuous-flow systems.
PFOA-linked bladder cancer signals identified in transcriptomic analysis
