Overview

This research demonstrates a portable arsenic biosensor using Escherichia coli, highlighting its potential for water quality monitoring in low-resource communities.

Key Points

  • The biosensor detects arsenic concentrations as low as 5 µg/L, ensuring community access to essential health resources.
  • Validation studies on 61 samples revealed sensitivity of 98.1% and specificity of 99.0%, marking it highly reliable for public health monitoring.
  • The design includes paper-based bacterial modules and a 3D-printed housing, making it cost-effective and easy to replicate in rural settings.
  • The open-access model promotes sharing of critical knowledge like protocols and schematics, empowering local adaptations for arsenic surveillance.
