The research aims to develop a user-friendly, paper-based sensor for detecting lead and nitrite in water.
Designed a colorimetric microfluidic paper-based analytical device (µPAD)
Developed a desktop application for results reading
Tested the sensor with water samples from contaminated sites
The µPAD successfully detected lead and nitrite levels in water
Provided a quick and cost-effective solution for preliminary water testing
Abstract
This paper-based tool aims to provide a simple do-it-yourself sensor for preliminary screening of common water pollutants at sites of highly contaminated water.
