Visual quantification of Hg on a microfluidic paper-based analytical device using distance-based detection technique [PDF]
AIP Advances, 2017 We presented a distance-based detection method for visual quantification of mercury ions on a microfluidic paper-based analytical device (μPAD). Dithizone in NaOH solution was used as chromogenic reagent and deposited onto paper channel delimited by hydrophobic wax barrier.
