Abstract:

The present invention is a process and apparatus for metal ion detection. The process of the invention has the steps of 1 disposing, in an analyte medium, a macromolecule suitable for selective complexation with the target metal ion species 2 disposing, in the analyte medium, an appropriate photoluminescent indicator that will emit in a measurably different manner when bound to the metallomacromolecule complex, compared with its unbound state 3 exciting the photoluminescent indicator species and 4 monitoring the emission of the photoluminescent indicator species to detect changes in its emission. The apparatus of the invention has I a macromolecule suitable for selective complexation with the target metal ion species disposed in an analyte medium 2 an appropriate photoluminescent indicator that will emit in a measurably different manner when bound to the metallomacromolecule complex, compared with its unbound state, also disposed in the analyte medium 3 a source for exciting the photoluminescent indicator species and 4 a detector for monitoring the emission of the photoluminescent indicator species to detect changes in its emission.
