Each year, lab technicians use ion-selective electrodes (ISEs) to make more than 1 billion measurements of ion concentrations in biological and environmental samples, according to industry estimates. Those measurements, which are typically made with engineered lab instruments costing hundreds of dollars or more, might soon be made in the field with inexpensive, disposable paper-based systems.
