Abstract:
Ionophore-based dye liquid nanoemulsion sensors exhibiting rapid response, high selectivity, and high sensitivity to chloride were developed. Since nanoemulsions contain extremely high concentrations of dyes and have large surface areas, rapid and highly sensitive measurements were possible. 1H-NMR measurements revealed intermolecular interactions between the dye and the ionophore, which contributed to the suppression of the background signal.
