ABSTRACT:
An optical indicator for determining the activity of an ion in a sample is provided with an ionophor which is capable of selectively binding the ion to be measured. The ionophor has at least two functional groups that can form an electron donor acceptor (EDA) complex, the complex bond being broken up by the attachment of the ion to be determined. This will lead to a change in at least one of the measurable optical properties of the indicator in dependence on the activity of the ion to be measured.
