Abstract
Starch films containing a chemodosimeter probe based on a quinolinium merocyanine dye were successfully prepared and studied. Through the selective nucleophilic addition reaction between cyanide anions and the dye chromophore the film can selectively detect sub-micromolar quantities of cyanide ion by a distinct color change.
