Background:

Arsenic contamination in groundwater poses a global health risk.
Accurate and accessible field detection methods are crucial for public safety.

Purpose of the Study:

To develop a cost-effective, highly sensitive, and portable assay for on-site arsenic detection in water.
To enable rapid identification of safe wells and aid in global arsenic mapping.

Main Methods:

A novel paper-based fluorescence assay utilizing the solid-phase fluorescence filter effect (SPFFE).
Generation of silver nanoparticles (AgNPs) induced by arsine (AsH3) interacting with carbon dots.
Integration with a smartphone and a portable sensing platform for field analysis.

Main Results:

Achieved a low arsenic detection limit of 0.36 μg/L.
Demonstrated high sensitivity due to efficient Ag+ reduction and AgNP properties.
Validated accuracy against mass spectrometry for surface and groundwater samples.

Conclusions:

The developed SPFFE-based assay offers excellent sensitivity, portability, and low cost for arsenic analysis.
This system holds significant potential for widespread on-site water quality monitoring.
Facilitates rapid assessment of groundwater safety and contributes to global arsenic contamination mapping.
