Multi-ion imaging using fluorescent sensors in a microtiterplate array format

Zusammenfassung

A novel type of sensor array destined for water analyses is described. The sensor delivers simple on/off patterns of complex ion mixtures. Fluorescent indicators for Ca2+, Na+, Mg2+, SO42-, Cl- and Hg2+ were arranged in microtiterplates and the analytical information was imaged with a CCD camera within microseconds using an intrinsically referencing method.
