Abstract
An embodiment provides a method for measuring an analyte component of an aqueous sample, including: introducing an indicator solution to the aqueous sample, wherein the indicator solution comprises a plurality of micelles, wherein an indicator is within the micelles and the plurality of micelles is assembled from a cationic surfactant to form an indicator solution; and measuring an analyte component concentration of the aqueous sample, wherein the measuring comprises measuring a change in fluorescence in the aqueous sample, wherein the change in fluorescence is responsive to the analyte component interacting with the indicator. Other aspects are described and claimed.

A method for measuring an analyte component of an aqueous sample, comprising:
- introducing an indicator solution to the aqueous sample, wherein the indicator solution comprises a plurality of micelles, wherein an indicator is within the micelles and the plurality of micelles is assembled from a cationic surfactant to form an indicator solution;
- and
- measuring an analyte component concentration of the aqueous sample, wherein the measuring comprises measuring a change in fluorescence in the aqueous sample, wherein the change in fluorescence is responsive to the analyte component interacting with the indicator, wherein the analyte component concentration is less than 100 parts-per-billion (ppb).
A composition for measuring an analyte component in an aqueous sample, comprising:
- a silane-fluorophore complex indicator;
- and
- a plurality of micelles, wherein the silane-fluorophore complex indicator is within the micelles and the plurality of micelles is assembled from a cationic surfactant, wherein the analyte component concentration is less than 100 parts-per-billion (ppb).
A composition for measuring fluoride in an aqueous sample, comprising:
- a silane-fluorophore complex indicator, wherein a change in fluorescence is based upon an interaction of the silane-fluorophore complex indicator and an amount of fluoride in the aqueous sample, wherein the amount of fluoride is less than 100 parts-per-billion (ppb);
- and
- a plurality of micelles, wherein the silane-fluorophore complex indicator is within the micelles and the plurality of micelles is assembled from a cationic surfactant.
