title: A prototype point-of-use assay for measuring heavy metal contamination in water using time as a quantitative readout.
abstract: This Communication describes a prototype quantitative paper-based assay that simultaneously measures the levels of Pb(2+) and Hg(2+) in water. The assay requires only measurements of time to yield a quantitative readout, and the results are independent of sample volume, humidity, and sample viscosity.
