Abstract

We report on the results of a combinatorial approach for the optimization of materials for use in fluorescent sensing of metal ions, primarily alkali ions. The sensor materials studied are composed of a hydrogel containing an emulsion of a lipophilic plasticizer, the latter incorporating an ion carrier and a polarity-sensitive dye that acts as a fluorescent reporter probe. The carriers were ...
