Reconfigurable Au Nanoparticle Monolayers on Regenerated Cellulose Hydrogels: Highly Sensitive SERS Detection of Polystyrene Micro/Nanoplastics With Interpretable Deep Learning

Advanced Functional Materials, EarlyView.
A regenerated cellulose (RC) hydrogel‐based SERS substrate integrating a Marangoni‐transferred gold nanoparticle self‐assembled monolayer (Au‐SAM) is fabricated. Reswelling‐induced hotspot formation enhances polystyrene micro/nanoplastics (PS MNPs) detection in complex matrices, providing reproducible, high‐throughput SERS signals across diverse ...

Contribution of atmospheric deposition to heavy-metal concentrations in field crops.

Netherlands Journal of Agricultural Science, 1990
Lolium multiflorum, spring wheat cv. Adonis, carrots and spinach were grown in the field and in a dust-free growth chamber in pots containing soil labelled with 109Cd and 210Pb. The contribution of atmospheric Cd and Pb deposition to plant concn was examined by isotope dilution.
