Potentiometric determination of lead ions using Pb2+-ion selective electrodes (ISEs) is hindered when coupled with unmodified microfluidic sampling paper-based substrates. In such instance, the super-Nernstian response of the electrode is believed to be caused by interactions between lead ions and f...
